Biorganic Carapace + Mind Over Matter + Lithoform Engine

Biorganic Carapace

Mind Over Matter

Lithoform Engine

How it works

1. Deal combat damage to an opponent using the creature that has Biorganic Carapace attached, triggering it.
2. Holding priority, activate Lithoform Engine by paying 2 and tapping it, copying the creature's trigger.
3. Resolve the copy of the creature's ability, drawing a card for each modified creature you control.
4. Holding priority, activate Mind Over Matter by discarding a card, untapping Lithoform Engine.
5. Activate Mind Over Matter by discarding a card, untapping a mana-producing permanent.
6. Activate the mana-producing permanent by tapping it, adding 1.
7. Repeat from step 5 one additional time.
8. Repeat from step 2.

This fascinating loop turns a single combat strike into an endless cascade of cards and mana. When your creature equipped with Biorganic Carapace deals combat damage to an opponent, its modified status triggers a card-drawing boon. Instead of just letting that trigger resolve normally, you pay two mana to tap Lithoform Engine and copy it, doubling your intellectual harvest. To keep the engine running, Mind Over Matter steps in to let you discard cards to untap both Lithoform Engine and whichever mana-producing permanent you used to fund the copy, easily generating the necessary mana and fueling the exact discards you need to feed the cycle over and over again.
