Selvala, Heart of the Wilds + Intruder Alarm + Mortuary + Kroxa, Titan of Death's Hunger

Selvala, Heart of the Wilds

Intruder Alarm

Mortuary

Kroxa, Titan of Death's Hunger

How it works

1. Cast Kroxa by paying .
2. When Kroxa enters the battlefield, it triggers twice, as well as Intruder Alarm and Selvala.
3. Resolve the Intruder Alarm trigger, untapping all creatures.
4. Activate Selvala by paying and tapping it, adding 3.
5. Resolve the first Kroxa trigger, causing you to sacrifce it.
6. When Kroxa dies, Mortuary triggers, putting Kroxa on top of your library from your graveyard.
7. Resolve the second Kroxa trigger, causing each opponent to discard a card and then lose three life if they didn't discard a nonland card.
8. Resolve the Selvala trigger from step 2, causing you to draw Kroxa from your library.
9. Repeat.

This ingenious loop centers around casting Kroxa, Titan of Death's Hunger over and over, turning its self-sacrificing nature into an unstoppable engine. Every time Kroxa enters the battlefield, Intruder Alarm untaps all your creatures—including Selvala, Heart of the Wilds—allowing Selvala to repeatedly tap for a massive burst of mana fueled by Kroxa's high power. Meanwhile, Mortuary ensures that the moment Kroxa goes to the graveyard, it safely returns right to the top of your library instead, where Selvala's card-draw trigger can pluck it back into your hand.
