Solar Array + Rise and Shine + Pemmin's Aura

Solar Array

Rise and Shine

Pemmin's Aura

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.

To set this machinery into motion, you first animate Solar Array into a creature so it can legally bear Pemmin's Aura. Once enchanted, tapping Solar Array for blue mana triggers its delayed ability to grant sunburst to your next artifact spell, while Pemmin's Aura happily untaps the Array for the cost of that very same blue mana. By looping this untap-and-tap cycle endlessly, Solar Array builds up an infinite history of mana spent with different colors—or simply an arbitrarily large stack of sunburst applications waiting for the payoff. When you finally cast a spell like Rise and Shine, that accumulated sunburst turns your animated artifacts into towering threats overflowing with infinite counters.
