Silver Surfer, Galactus's Herald (MSC-010) - Commander: Marvel Super Heroes

Flying

When Silver Surfer enters, you may search your library for a card named Galactus, Devourer of Worlds, reveal it, put it into your hand, then shuffle.

Whenever Silver Surfer deals combat damage to a player, until the end of your next turn, target creature attacks that player each combat if able.
