Mortuary + Blasting Station + Aetherflux Reservoir + Gwenom, Remorseless

Mortuary

Blasting Station

Aetherflux Reservoir

Gwenom, Remorseless

How it works

1. Activate Blasting Station by tapping it and sacrificing a creature
2. When the creature dies, Mortuary triggers, putting the creature from your graveyard onto the top of your library.
3. Resolve the Blasting Station ability.
4. Cast the creature from the top of your library by paying X life, where X is the creature's mana value.
5. Aetherflux Reservoir triggers, causing you to gain 1 life for each spell you've cast this turn.
6. When the creature enters, Blasting Station triggers, untapping Blasting Station
7. Repeat.

This clever engine leverages Mortuary to instantly recycle any creature sacrificed to Blasting Station right back to the top of your library. From there, Gwenom, Remorseless grants you the ability to recast that creature directly off your library, bypassing its mana cost by paying life instead. Meanwhile, Aetherflux Reservoir tracks your rapidly escalating storm count, cushioning the life you spend with massive lifegain triggers until you have enough surplus to point a lethal 50-damage blast at any target.
