It's a Scarf Regenerator Chomp. U-Turn out and heal up! But seriously though, I need help with the last move, and any changes that you would make to the item (though I would like Regenerator and U-Turn to stay if possible). I was thinking Sunsteel Strike to beat Sturdinja, but I don't know.
Sharknado 10 (Garchomp-Mega) @ Choice Scarf Ability: Regenerator EVs: 252 HP / 252 Atk / 252 Def / 252 SpD / 252 Spe Jolly Nature - U-turn - Dragon Hammer - Thousand Arrows - ???
Thanks, and have a great day!
Give it a choice band, adaptability, and adamant nature for more power. Forget thousand arrows and teach precipice blades for even more power and bolt strike to cover flying. Use equations like y=ax^p (or y=axp if you like fancy HTML formatting) for still more power.
