4/5 Hydra Heads Recommend Colgate

Power Level: 7
 
Piloting Difficulty: 2
 
Strategy: You'll want to play as many creatures as possible to buff animar, so that your hydras can be even bigger. There is tons of creature based card draw, so your hand should stay full.
And then go to town with those hydras!
 
TLDR Strategy: Big creatures make even bigger creatures.
 
Weaknesses: Creature control. You will often dump a majority of your resources for the turn into a big spell. A well timed counter by an opponent will set you back a turn if you aren't careful.
It is also weak against aggro, as it's boardstate gets bigger with time.
