not 100% sure bout the moveset yet(more 60% sure), but this is it for now:
reunicleus with psychic, recover, energy ball (dont know the last one)
samurott with icebeam, hydro pump, aqua tail and aerial ace
unfezant with sky attack, aerial ace, roost (dont know the last one)
chandelure with shadow ball, flamethrower(dont know the next 2 yet)
zekrom with fusion bolt, thunderbolt, dragonbreath and zen headbutt
i personally hate grass because its easy to counter them, and others can do their job. but maybe ferrothorn?
