I am Iron Man

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.)

Search your hand, graveyard, and library for
an Infinity Stone Artifact, reveal it, put it
onto the battlefield tapped, then shuffle your library. Then, if you control six unique Infinity Stone Artifacts, you win the game.
