Devastating Tide, however, has its own advantages. It temporarily solves the problem of the board state, but for significantly cheaper costs. 3UU is easily achievable for a deck that plays a 7 mana sweeper. The Miracle cost at 1U is even better because you could bounce everything and still have enough mana to pay for a Spell Pierce or Daze, or even play a Sylvan Scrying/Expedition Map. That should give you a massive tempo advantage in that they have to replay everything that they had in play. They'll likely be back where they were in 2-3 turns, perhaps longer if they had equipment to replay and equip.
Tide might not be as devastating (irony..) as All is Dust but it seems like they will both ultimately give you the same advantage in the long run; All is Dust solves the problem of the board state but for a heavy cost of 7, while Devastating Tide temporarily solves the problem of the board state, but for a minute cost that allows you to do other things with the same turn. As long as the board state doesn't threaten a win, 3 turns could be all you need to get a Primeval Titan into play and from there the game should pretty much be sealed. Also, Tide can be played quite early in the opponent is playing a really aggressive deck; however, I think those decks will have an easy time replaying their stuff. Goblins, play Lackey and something, go, swing in next turn, etc. 3 Turns later they have the same board state if not better than they had before. Elves/Affinity.. have no trouble reshitting their whole hand, also I'd say about 3 turns. I don't know if thats enough time.
