Dualcaster Mage + Echo Storm + Biotransference

Dualcaster Mage

Echo Storm

Biotransference

How it works

1. Cast Echo Storm by paying 3, targeting Dualcaster Mage.
2. Echo Storm triggers, creating a copy of itself, targeting Dualcaster Mage.
3. Resolve the copy of Echo Storm, creating a token copy of Dualcaster Mage.
4. When the Dualcaster Mage token enters the battlefield, it triggers, creating a copy of Echo Storm, targeting Dualcaster Mage.
5. Repeat from step 3.

This clever loop transforms a solitary sorcery into an endless echoing parliament of mages by weaponizing the passive rules interaction provided by Biotransference. Because Biotransference turns creature spells and cards into artifacts everywhere—including on the stack—casting Echo Storm allows it to target Dualcaster Mage sitting right there on the battlefield. When the original Echo Storm resolves and conjures a token copy of Dualcaster Mage, that token enters the battlefield and instantly triggers its own spell-copying ability to recreate Echo Storm, restarting the entire chain. You can repeat this sequence as many times as you desire, effortlessly generating infinite creature tokens, endless entry triggers, and as many magecraft activations as your strategy requires.
