Mortuary + Blasting Station + Willow Geist + Gwenom, Remorseless

Mortuary

Blasting Station

Willow Geist

Gwenom, Remorseless

How it works

1. Activate Blasting Station by tapping it and sacrificing Willow Geist.
2. When Willow Geist dies, it and Mortuary triggers.
3. Resolve the Mortuary trigger, putting Willow Geist from your graveyard onto the top of your library.
4. Resolve the Willow Geist trigger, causing you to gain 1 life
5. Resolve the Blasting Station ability.
6. Cast Willow Geist from the top of your library by paying 1 life due to Gwenom.
7. When Willow Geist enters, Blasting Station triggers, untapping Blasting Station.
8. Repeat.

This clever loop leverages Mortuary to instantly recycle any creature sent to the graveyard back to the top of your library. Gwenom, Remorseless makes casting that recycled creature effortless by letting you play it directly from the top, replacing traditional mana costs with a minor life payment. Meanwhile, Blasting Station provides the necessary sacrifice outlet and deals the fatal damage, while automatically untapping each time your creature re-enters the battlefield. Finally, Willow Geist acts as the perfect engine fodder, growing larger with its +1/+1 counters as it repeatedly leaves the graveyard to fuel an infinite storm and damage barrage.
