For lack of a good name, I guess I'll call this Blockeldurr
Conkeldurr @ Flame Orb
Ability: Guts
EVs: 236 Hp / 252 Atk / 20 Spe
Adamant Nature
- Drain Punch
- Mach Punch
- Block
- Knock Off / Fling / Coverage
The idea is to use Block on a predicted switch in so that you can buy yourself a free turn by switching in a check/counter to whatever switches in. The last move's up to you: Knock Off because it's Knock Off, Fling to take advantage of your lack of an Assault Vest for a free burn, or just a random coverage move.
EDIT: The EVs are basically just the AV EVs only 236 HP instead of SpD. It could probably be optimized in some way; I was focused more on the move set than anything else
