Solar Array + Pemmin's Aura + Trazyn the Infinite

Solar Array

Pemmin's Aura

Trazyn the Infinite

How it works

1. Activate Trazyn using Solar Array's ability by tapping it, adding and causing the next artifact spell you cast this turn to have sunburst.
2. Activate Pemmin's Aura by paying , untapping Trazyn.
3. Repeat as desired.
4. 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.

With Trazyn the Infinite on the battlefield and Solar Array resting quietly in your graveyard, Trazyn inherits the Array's activated ability thanks to Prismatic Gallery, allowing it to tap for mana. Enchanting Trazyn with Pemmin's Aura gives you a clean way to funnel that mana right back into untapping the legendary Necron, creating an infinite loop of taps and untaps. Because Trazyn's borrowed ability also tracks the condition of casting your next artifact spell with sunburst, you can prime this loop to make your upcoming artifact entries arbitrarily large. When you finally cast an artifact, Solar Array's delayed trigger stacks up infinitely, bestowing an overwhelming number of +1/+1 or charge counters upon your new permanent.
