Delina, Wild Mage + Ashnod's Altar + Strionic Resonator + Pestermite

Delina, Wild Mage

Ashnod's Altar

Strionic Resonator

Pestermite

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 Pestermite.
3. Resolve the copy of Delina's trigger, creating at least one token copy of Pestermite.
4. When the Pestermite 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 Pestermite token, adding CC.
6. Repeat from step 2.

This explosive combination turns a simple attack into a self-sustaining engine by marrying Delina, Wild Mage with the untap triggers of Pestermite. Every time Delina attacks, Strionic Resonator steps in to multiply the triggers, ensuring that your token copies of Pestermite flood the board and untap your artifacts and lands along the way. Meanwhile, Ashnod's Altar is right there to sacrifice those incoming tokens for colorless mana, easily paying for the Resonator's activation cost and fueling the loop indefinitely.
