Hullbreaker Horror + Selvala, Heart of the Wilds + Frostcliff Siege

Hullbreaker Horror

Selvala, Heart of the Wilds

Frostcliff Siege

How it works

1. Activate Selvala by paying and tapping it, adding at least 1 plus enough mana to cast a creature card from your hand.
2. Cast a creature card by paying its mana cost.
3. Hullbreaker Horror triggers, returning Selvala from the battlefield to your hand.
4. Cast Selvala by paying 1.
5. Hullbreaker Horror triggers, returning the creature cast in step 2 from the battlefield to your hand.
6. Repeat.

This clever loop relies on Hullbreaker Horror acting as a relentless bouncer whenever you cast a spell, letting you continuously recycle your pieces. By pairing it with Selvala, Heart of the Wilds, whose activated ability generates a surge of mana based on your highest creature power, you fund the casting costs required to keep the engine spinning. As you repeatedly cast and recast your creatures, Frostcliff Siege can optionally lend its Temur mode to grant your squad hasty aggression and trampling force, though the true engine simply thrives on the endless cycle of entering and leaving the battlefield.
