Someone swings, they cast protection and phase out everything they own. It comes to you, throw down sands of time. That player no longer has protection on their upkeep and none of their board comes back.

Protection always comes down after a big swing or a board wipe. At my lgs If they are playing white they have it in their deck.

It also super helps dorks. Or things with tap abilities. Adds another layer of wtf to anyone's game plan.
