Solar Array + Pemmin's Aura + Karn, the Great Creator

Solar Array

Pemmin's Aura

Karn, the Great Creator

How it works

1. Animate Solar Array, if needed.
2. Cast Pemmin's Aura by paying its mana cost, attaching it to Solar Array.
3. Activate Solar Array by tapping it, adding and causing the next artifact spell you cast this turn to have sunburst.
4. Activate Pemmin's Aura by paying , untapping Solar Array.
5. Repeat from step 3 as desired.
6. Cast any artifact spell, triggering its sunburst ability an infinite number of times, either putting infinite +1/+1 counters on charge counters on the artifact.

This loop transforms a humble mana source into a boundless engine by turning artifact manipulation into an infinite-mana and counter-generating machine. First, you rely on Karn, the Great Creator's +1 ability to animate Solar Array into an artifact creature, setting the stage for it to be enchanted. Once Pemmin's Aura is attached to the array, its untap ability provides the exact blue mana needed to sustain the loop indefinitely, since Solar Array's tap ability produces the required mana while simultaneously stacking up a deferred sunburst effect. Because Solar Array keeps granting future artifact spells sunburst each time it's tapped and untappd, you can eventually drop any artifact spell to flood the board with infinite charge counters or infinite +1/+1 counters.
