Galactus' Arrival

Vanishing 4 (This enters with four time counters. At the beginning of your upkeep, remove one. When the last is removed, sacrifice it.)

At the beginning of your precombat main phase, exile the top card of your library. Until end of turn, you may cast it. If you suspend a card this way,
draw a card. If you did not cast any cards this way, shuffle it back into your library.
