Ith, High Arcanist

Vigilance

[Tap]: Untap target attacking creature. Prevent all combat damage that would be dealt to and dealt by that creature this turn.

Suspend 4-[W][U] (Rather than cast this card from your hand, you may pay [W][U] and exile it with four time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost. It has haste.)
