Delina, Wild Mage + Ashnod's Altar + Strionic Resonator + Deceiver Exarch

Delina, Wild Mage

Ashnod's Altar

Strionic Resonator

Deceiver Exarch

How it works

1. Declare Delina as an attacker, triggering its ability, targeting any creature.
2. Holding priority, activate Strionic Resonator by paying 2 and tapping it, copying Delina's trigger, with the copy targeting Deceiver Exarch.
3. Resolve the copy of Delina's trigger, creating at least one token copy of Deceiver Exarch.
4. When the Deceiver Exarch token(s) enter the battlefield, they trigger, untapping Strionic Resonator and up to one other applicable permanent for each remaining trigger.
5. Activate Ashnod's Altar by sacrificing a Deceiver Exarch token, adding CC.
6. Repeat from step 2.

This chaotic masterpiece hinges on Delina, Wild Mage and her knack for replicating our best assets, though we need a little help to keep the dice rolling. By using Strionic Resonator to double Delina's attack trigger, we target Deceiver Exarch, whose entry trigger untaps the very Resonator we just tapped along with whatever else we might need. Ashnod's Altar steps in to quietly process those newly minted Exarch tokens into a tidy sum of colorless mana, fueling further Resonator copies and keeping the loop spinning indefinitely.
