Paradox Barrier

Whenever a player casts a spell, you may exile that spell with X time counters on it, where X is that spell's converted mana cost. If it doesn't
have suspend, it gains suspend. If you do, that spell's controller gets an emblem with: "After your first upkeep step each turn, there's an additional upkeep step."
Only when you start to think there is no way out, you finally escape from it.
