How it works
Prerequisites
- You control at least eight creatures if Mechanized Production is attached to a creature other than Deceiver of Form, or nine creatures otherwise.
- You have an artifact creature card on top of your library.
Steps
- 1At the beginning of your combat phase, Deceiver of Form triggers, revealing the top card of your library and causing all other creatures you control to become a copy of that creature until end of turn.
- 2At the beginning of your postcombat main phase, Shadow of the Second Sun triggers, causing you to get an additional beginning phase after this one.
- 3At the beginning of the extra upkeep phase, Mechanized Production triggers, creating a token copy of the artifact it is attached to and causing you to win the game.
