I will concede that once you have enough mana, the tide tends to be better because it is 2 less mana (but the UU is what kills it for me) and All is Dust's permanence is a lot more satisfying.
If Team America takes off more, cyclonic rift bouncing a tombstalker is really good. It'll buy at least 2-3 turns for 1U while repeal would need 8U.
