Tyrunt's unique Rock / Dragon typing and one of the most viable Dragon types in LC. Having access to Dragon Dance as well as Strong STABs makes it a notable wallbreaker that can easily pierce teams. The Sturdy ability, versatile HP range and high defenses allow it to set up more easly then other Dragon Dancers such as Axew, Corphish and Scraggy. Tyrunt also has access to STAB Dragon Tail and Stealth Rock, making it an effective phazer, despite it's competition with Onix and Hippopotas.
name: Dragon Dance Sweeper
move 1: Dragon Dance
move 2: Outrage / Dragon Claw
move 3: Stone Edge / Rock Slide
move 4: Earthquake / Zen Headbutt
item: Berry Juice
evs: 204 Atk / 76 SpD / 212 Spe
Tyrunt has Dragon Dance to combine with 15 Speed letting it out speed the entire unboosted metagame after a Dragon Dance. A +1 STAB Outrage is able to pick up the KO on the vast majority of his checks, Dragon Claw however is useful if Tyrunt's counters like Ferroseed/Fairy types aren't easily removed sadly it lacks power. Rock Slide has good accuracy and picks up all the important KO's that Stone Edge would, Stone Edge however does see noticeable difference in damage out put, but its accuracy leaves it as a secondary choice. Earthquake is useful to ensure neutral and wide super effective coverage in combination with Rock Slide/Stone Edge. Zen Headbutt on the other hand allows you to 2HKO fight/Poison-Types without being locked into Outrage.
23 HP IV's are necessary to get optimal use of Berry Juice and Sturdy to give you optimal set up opportunity. The EV's give Tyrunt 15 Speed and optimal Attack. Jolly nature allows it to outspeed scarfed 14 speed users. The remaining IV's can be put in either Defense or Special Defense as both have slight influence in reducing damage.
If Tyrunt's ability and item have preserved correctly it will give set up opportunities against practically anything but you should aim to set up against Normal- or Flying-types. Don't set up until Tyrunt's counters and checks have been hit by Knock Off or weakened, as then the extra power from Dragon Dance will allow for a sweep. Using Memento or Parting Shot creating more of a set up opportunity is helpful but not necessary. Try scouting for potential checks like Choise Scarfed Mienfoo or anything able to outspeed after a +1 boost.
Gothita and Wynaut are fine choices for eliminating fighting-types, Wynaut can also turn pokemon into set up bait with encore.
Croagunk and Pancham can be useful for luring in or eliminating Fairy types like Spritzee by hitting it with super effective Poison-type attacks or Knock Off making it much easier to sweep later in game, Pancham can also make use of Parting Shot allowing it to create set up opportunity. Entry hazard setters such as Ferroseed or Trubbish will help Tyrunt achieve some more KOs. Notably Cottonee is able to proving good synergie threatening the majority of checks as well as providing Memento, Stun Spore and Knock Off support.
Spritzee can again be used as a strong allies as it can Wish pass and Heal Bell keeping Tyrunt status free and Healthy. Having some form of hazard control with Rapid Spin or Defog on the team is essential meaning Drilbur and Vullaby are nice cut for this job. Finally Knock Off users like Pawniard make good allies as they are able to weaken the opposing team making sweeping with or without boost much easier, Pawniard in particular makes a good ally as it reliably deals with fairy types and baits all the other answers to Tyrunt allowing you to weaken them. Same counts counts for Magnemite who in addition can scout for set up chances with Volt-Switch.
name: Stealth Rock Phazer
move 1: Stealth Rock
move 2: Dragon Tail
move 3: Stone Edge / Rock Slide
move 4: Earthquake / Brick Break / Zen Headbutt
item: Berry Juice
evs: 204 Atk / 60 Def / 212 Spe
STAB Dragon Tail can be utilized to punish switch-ins giving it an edge in damage output over other Phazers. Stone Edge is Tyrunt's strongest STAB move for this set, Rock Slide can be used as well for more accuracy but this lacks damage output. The last move Earthquake in combination with Stone Edge makes one of the best coverage combinations in the game. Zen Headbutt is amazing coverage in this tier, with Tyrunt's high physical attack it's able to 2HKO the vast majority of the tier after after being weakened by Stealth Rock damage including it's answers Pancham and Timburr. Brick Break on the other hand can be used to 1HKO Pawniard.
23 HP IV's are necessary to hit 21 HP allowing full HP to be restored after being knocked into the Sturdy ability.The EV investment is to maximize it's speed allowing it to outspeed the 14 speed tier including Magnemite and offencive Vullaby. The Attack investment is to gain optimal damage output. The remaining EV's are put into Defense making it deal better with Flying Types. If there is Wish support on the team it should be considered to use Eviolite with a spread of 52 HP/ 204 Atk / 140 Def / 76 Spd.
Tyrunt has the usefull Berry Juice and Sturdy combination ensuring it to survive 2 hits. Because of this usefull combination the user should keep Tyrunt's HP at maximum at all costs, this includes having Hazard controll as this is the easiest way to shut down the ability. Take opportunities to set up Stealth Rock or use Dragon Tail if it's already up. It should phaze every opponant it can't ensure the kill on, this way you weardown your opponant for your allies and also prevent him from defogging or spinning your Stealth Rocks away. You have watch out for Fairy types not only do they shut you down from using Dragon Tail but they also can take advantage of your weakness.
For the Eviolite set; Spritzee is the best partner as it can switch into Fighting-type attacks, keep Tyrunt alive with Wish allowing Tyrunt to take better advantage of Eviolite and could eliminating status what is a general positive to the team. In addition, Spritzee could use Calm Mind as well taking advantage of the worn down opponents. The Berry Juice version wants to have Rapid Spinners and Defoggers like Vullaby as these ensure the Sturdy ability stays active. Other options such as Magnemite, Pawniard, and Skrelp can tank the Steel- and Fairy-type attacks aimed at Tyrunt while Tyrunt can absorb Fire-type attacks for the former two. Pumpkaboo is immune to Fighting and resists Ground while also being a spinblocker to keep Stealth Rock up against Drilbur and Staryu. Lastly, Trubbish can take on Fighting- and Fairy-types ,absorb Knock Off ensuring Berry Juice stays up and putting Spikes or Toxic Spikes to build up on Dragon Tail damage. In addition, Skrelp can also set up Toxic Spikes.
Choise Scarf can be used to turn Tyrunt into an effective revenge killer as it can hit 15 speed or 19 attack, Sadly it lacks damage output compared to what the Dragon Dance-set can do. A completely different set with 52 HP / 124 Atk / 76 SpD / 212 Spe, Adamant nature holding Eviolite and utilizing the Strong Jaw ability can be used for the Dragon Dance-set and allows you to make use of Fire Fang over EQ/ZHB to deal with Ferroseed as well as Cottonee and Ice Fang to heavily damage Ground-types. A Rest and Sleep Talk set allows for a more durable approach but it lacks coverage as you want to run Dragon Tail/Earthquake and Stone Edge, Dragon Tail in this prevent you from being set up bait against anything but Fairy-types. In addition Curse can be combined with Dragon Tail allowing you to slowly wither down the opponent, but completely blocked by Fairy-types. Rock Tomb can be used on the Phaze-set giving further support as well as letting it outspeed anything unboosted in the metagame. Finally Iron Tail gives coverage against Fairy-types but has unfortunate accuracy and hits little else.
Checks and Counters
**Fairy-types**: Fairy-types such as Spiritzee and Snubbull both threaten Tyrunt with their super effective STAB moves, while being immune to Tyrunt's Dragon STAB moves. Cottonee especially can be worrisome as it can make Tyrunt set up bait with Encore and Memento.
While they should watch out for Iron Tail, this still doesn't always pick up a 2HKO on Snubble and Spritzee.
**Ground-types**: Ground-Types such as Hippopotas and Drilbur deal heavy damage to Tyrunt with super effective STAB moves and posses the bulk necessary to threaten both set options. Drilbur can hit trough Sturdy and Rapid Spin away Stealth Rocks. While Hippopotas can Phaze the Dragon Dance set, sadly gets phazed out by Dragon Tail for the Phazing set.
The multitude of strong Fighting-types such as Timburr, Mienfoo, Pancham, and Scraggy all give Tyrunt major trouble.
They can easily check the Dragon Dance set if it lacks Zen Headbutt by damaging and recover at the same time with a Super effective Drain Punch or Knock Off its Berry Juice.
**Steel-types**: While they should be wary of Earthquake, Magnemite with Sturdy can switch in on anything as long as it has not taken any prior damage, and can threaten with Flash Cannon. Pawniard threatens the Stealth Rock set if it lacks Brick Break, Scarf Pawniard outspeeds +1 Tyrunt and can remove or heavily damage Tyrunt with Knock Off and Iron Head respectively. Lastly Ferroseed only has to watch out for a Strong Jaw set with Fire fang as it's able to take any other attack, punish Outrage thanks to Iron Barbs and shut down Tyrunt's speed with Thunder Wave.
