Seija, Immoral revolutionary

{c}Sacrifice a creature you control with power or toughness 1: Search your library for an artifact card. If it's an Equipment, attach it to Seija, otherwise, put it into your hand. Then shuffle your library.

When Seija would be removed from the battlefield, you may sacrifice an Equipment. If you do, Seija remains on the battlefield instead.

If Seija has 9 Equipment attached and you control 6 creatures with power or toughness 1, you win the game.
