Mortuary + Goblin Bombardment + Haywire Mite + Gwenom, Remorseless

Mortuary

Goblin Bombardment

Haywire Mite

Gwenom, Remorseless

How it works

1. Activate Goblin Bombardment by sacrificing Haywire Mite.
2. When Haywire Mite dies, it and Mortuary triggers.
3. Resolve the Mortuary trigger, putting Haywire Mite from your graveyard onto the top of your library.
4. Resolve the Haywire Mite trigger, causing you to gain 2 life
5. Resolve the Goblin Bombardment ability.
6. Cast Haywire Mite from the top of your library by paying 1 life due to Gwenom.
7. Repeat.

This looping machinery hinges on Mortuary, which quietly catches your creatures as they perish and safely tucks them right back onto the top of your library. From there, Gwenom, Remorseless grants you the vital permission to cast that creature straight off the top of your library, trading mana for life payments that are easily sustained by the steady 2 life you gain each time Haywire Mite dies. Goblin Bombardment provides the sacrificial outlet to trigger this entire engine while turning your recycling loop into an endless stream of damage to any target.
