Hidetsugu, Devouring Chaos + Intruder Alarm + Arcbound Reclaimer + Arcbound Ravager

Hidetsugu, Devouring Chaos

Intruder Alarm

Arcbound Reclaimer

Arcbound Ravager

How it works

1. Activate Arcbound Ravager by sacrificing itself.
2. Arcbound Ravager dies, triggering its modular ability, putting all +1/+1 counters from it onto Arcbound Reclaimer.
3. Activate Arcbound Reclaimer by removing a +1/+1 counter from it, putting Arcbound Ravager from your graveyard on top of your library.
4. Activate all mana-producing creatures you control by tapping them, adding at least 4.
5. Activate Hidetsugu's second ability by paying 2 and tapping it, exiling Arcbound Ravager from the top of your library with the ability to cast it from exile this turn, and dealing 2 damage to any target.
6. Cast Arcbound Ravager from exile by paying 2.
7. Arcbound Ravager enters the battlefield with a +1/+1 counter on it, triggering Intruder Alarm, untapping all creatures.
8. Repeat.
