Solar Array + Pemmin's Aura + March of the Machines

Solar Array

Pemmin's Aura

March of the Machines

How it works

1. Cast Pemmin's Aura by paying its mana cost, attaching it to Solar Array.
2. Activate Solar Array by tapping it, adding and causing the next artifact spell you cast this turn to have sunburst.
3. Activate Pemmin's Aura by paying , untapping Solar Array.
4. Repeat from step 2 as desired.
5. 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 March of the Machines turning all your noncreature artifacts into artifact creatures, Solar Array becomes a valid target for Pemmin's Aura to enchant. By tapping Solar Array for mana and using that exact mana to activate Pemmin's Aura's untap ability, you create an infinite mana loop that simultaneously powers up Solar Array's delayed trigger. When you finally unleash any artifact spell, Solar Array's accumulated sunburst instances will reward you with infinite counters of whichever kind you desire.
