How it works

1. Activate Luxurious Locomotive's crew ability by tapping four creatures you control with total power 1 or greater, causing Luxurious Locomotive to become an artifact creature until end of turn.
2. Declare Luxurious Locomotive and Fear of Missing Out as attackers, triggering their abilities.
3. Resolve the Luxurious Locomotive trigger, creating at least four Treasure tokens.
4. Resolve the Fear of Missing Out trigger, untapping Luxurious Locomotive and causing you to get an additional combat phase after this one.
5. Holding priority, activate Phyrexian Altar by sacrificing Fear of Missing Out, adding 1.
6. Activate two Treasures by tapping and sacrificing them, adding 1.
7. Activate Ruthless Technomancer by paying 2 and sacrificing two Treasures, returning Fear of Missing Out from your graveyard to the battlefield.
8. When Fear of Missing Out enters the battlefield, it triggers, causing you to rummage.
9. Repeat from step 2 each combat phase.
