Dragon Dance Krookodile
Common give this rageous monster the oportunity to set up a DD and you have a real late game sweeper. With moxie stab knock off and an awesome movepool is a better crawdaunt when it starts gettin moxies.
Poison heal and roost mantine are only the same walls but with more recovery, this changes krooks play style cause you don't need to be choice-locked anymore.
Drought thyplosion is also cool but only in OU weather abilities can be used and thyplosion in OU.....not the greatest idea.
