(Ochoa) Kalonian Hydra, individually, is a very good creature; that is, it's one that will win a game by itself if left unanswered, which isn't to say that it's not good in conjunction with other creatures. In fact, the Hydra works quite well with almost every card dealing with +1/+1 counters; Gavony Township; Mikaeus, the Lunarch; Forgotten Ancient; and Exava, the Bloodwitch for example. Attacking as an 8/8 followed by a 16/16 will certainly end most games quickly which is part of what makes the Hydra so good.
