Steve Rogers, Captain America

Infinity (Your Infinity Stone Artifacts can help
cast this spell. Each Infinity Stone Artifact you tap while casting this spell pays for one mana of your choice of this spell's casting cost.)
When Steve Rogers enters the battlefield, you may search your hand, graveyard and library
for a card named The Captain's Shield, reveal
it, and put it onto the battlefield attached to Steve Rogers. Then shuffle your library.

Vigilance, haste.
