Yes, I am well aware that other creatures can be rewind-ed, but with two graveyards there is bound to be at least one skeleton in play at any given time.
@ qazzaq123 except that having a skeleton that I could rewinding kept me from running out cards while my deck slowly, but surely, defeated my enemies while I remained relatively invincible. With that new update, my entire deck is now useless. But I guess that's what I get for having a very fine-tuned deck
