Remembrance + Mortuary + Goblin Bombardment + Crimson Kobolds

Remembrance

Mortuary

Goblin Bombardment

Crimson Kobolds

How it works

1. Activate Goblin Bombardment by sacrificing Crimson Kobolds.
2. When Crimson Kobolds dies, Mortuary and Remembrance trigger.
3. Resolve the Mortuary trigger, putting Crimson Kobolds from your graveyard on top of your library.
4. Resolve the Remembrance trigger, searching your library for Crimson Kobolds and putting it into your hand.
5. Resolve the Goblin Bombardment ability, dealing 1 damage to any target.
6. Cast Crimson Kobolds by paying 0.
7. Repeat.

This elegant loop relies on the zero-mana cost of Crimson Kobolds to immediately restart the cycle after you sacrifice it to Goblin Bombardment. Each time the Kobolds hit the graveyard, both Mortuary and Remembrance trigger simultaneously; Mortuary places the card right back onto the top of your library, while Remembrance lets you tutor a copy straight into your hand. Because Crimson Kobolds costs nothing to cast, you can replay it instantly to replace the one you sacrificed, turning those two enchantment triggers into an endless engine of damage and death triggers.
