That's the thing about druddigan. It has quite a few sets that can work for it. I find succes with my sheer force set, but I might try the rough skin set to see if it works better. The thing that I don't want happening is getting toxiced though. Oh ya and with electivire,it's kinda sad that he has such a wide variety of elemental moves, but he just doesn't have the attk power to KO stuff. I really like the electric gorilla. He'll probably stay in the RU of RU.
Then I recommend the Life orb set with 104 Evs in speed, unless the toxic user is faster eg- Gligar, Moltres or you happen to switch into a toxic, I can't help you there unless you also have a cleric on your team.
name: Physical attacker
move 1: Outrage / Dragon Claw
move 2: Earthquake
move 3: Suckerpunch
move 4: Taunt
Item: Life orb
Nature: Adamant
Ability: Rough Skin
EVs: 152 HP/ 252 Att / 104 Spe
I was thinking about how a Substitute set would work
name: Substitute
move 1: Substitute
move 2: Earthquake
move 3: Dragon tail / Dragon claw
move 4: Glare / Suckerpunch
Item: Leftovers
Nature: Adamant
Ability: Rough Skin
EVs: 152 HP/ 252 Att / 104 Spe
This set works a lot like other substitute sets, where you switch into something you threaten, set up a sub while they switch out their pokemon and switch in their Druddigon counter, from there you can proceed to counter them appropriately
If they switch in a Steel hit them with with EQ, if they switch in a physical wall like tangela or gligar, phaze them out with Dragon tail or just hit them with stab dragon claw. I don't think Tangela can even break your sub.
Gligar with no investment in attack can break your subs though , unless you run max 248 EVs in HP and 120 Evs in Def with impish nature ( I could be wrong, I'm terrible with damage calculations). 248 EVs in HP allows you to create 4 subs, leaving you with 1 hp.
The last slot really depends on your needs or your teams needs, Glare is a interesting option as it can paralyze the opposing pokemon if Dragon tail, Dragon claw and EQ happen to be bad options to use against your opponent at the time, Paralyze is almost always useful. Glare being a normal move, Ground types aren't immune to it like T-wave which make this unique and since Glare has been boosted to 90% accuracy, the move is more useful then not.
Suckerpunch is there as priority to hit faster pokemons, Toxic can be used in the last slot be but there are better pokemon which can spread toxic, mainly the 3 normal special walls.
The speed EVS allow you to outspeed the like of licklicky audio, tangela clefable and bulky ghost, preventing them from status-ing you.
