Jesus Christ Tyrantrum has some of the worst 4MSS I've ever seen. Anyways, I've put together two semi-unusual sets together; do you guys think it will work?
Bulky Offence@Assault Vest
Strong Jaw
Impish
252 Atk / 252+ Def / 4 HP
Stone Edge
Fire Fang
Dragon Claw/Dragon Tail/Crunch
Earthquake
The idea behind this is that since most of Tyrantrum's counters are physical priority users, Speed investments are wasted. Instead, it focuses on his strong suits. With the posted EV's, it has 306 HP, 341 Atk, and 370 Def, which I believe is sufficient for Bullet Punches and their ilk. With the Assault Vest, SpD reaches a meh 231, (347 in sand) which should suffice for non-STAB non-super effective moves. Maybe. Stone Edge and EQ make the excellent EdgeQuake combo, and he gets STAB on the former. Fire Fang/Dragon Claw gets perfect neutral coverage except for Heatran, Azumaril, and Carbink, none of which resist EQ. Dragon Tail is a possibility for phazing, and Crunch is if Ghosts are a problem.
Gleaming Dinosaur@Leftovers/Weakness Policy
Strong Jaw
Impish
212 Atk / 252+ Def / 44 Spe
Rock Polish/Dragon Dance
Stealth Rock/Ice Fang/Crunch
Stone Edge/Dragon Claw
Earthquake/Fire Fang
Forget about special defense; don't even try to pretend that you can take a special hit. The idea behind this set is to set up SR in the beginning, switch out, do stuff, switch in when there's a physical attacker who doesn't have STAB super effective moves, then make yourself gleam or do a jig. Making yourself gleam makes you outspeed positive nature base 122 (Greninja). Doing a jig allows you to outspeed positive nature base 100.
I'm extremely conflicted on the offensive moves. All of the follwing have niches/merit, and I really can't decide which would work best.
Stone Edge (STAB)
Dragon Claw (STAB)
Earthquake (Coverage)
Fire Fang (Coverage)
Ice Fang (Garchomp, Gliscor, and Dragonite)
Crunch (Gengar)
Thunderfang (Azumaril)
Poison Fang (Other Faries)
I would really appreciate feedback on the merit of these two sets, especially the latter.
