Garchomp @ Normal Gem
Ability: Rough Skin
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
-Dragon Claw
-Earthquake
-Facade
-Protect
Garchomp is total burn bait, but with Facade it now ignores burns and has a 140 BP attack, stronger than STAB Dragon Claw and with decent neutral coverage on most of the meta.
252 Atk Garchomp Dragon Claw vs. 252 HP / 0 Def Rotom-W: 124-147 (40.7 - 48.3%)
252 Atk Normal Gem Garchomp Facade (140 BP) vs. 252 HP / 0 Def Rotom-W: 187-221 (61.5 - 72.6%)
Dragon Claw never activates Sitrus, then Normal Gem Facade always kills from the remainder after Rotom-W burns you.
If you want to be REALLY baller use this set.
