Lux Artillery + Crystalline Crawler + Meticulous Excavation

Lux Artillery

Crystalline Crawler

Meticulous Excavation

How it works

1. Cast Crystalline Crawler by paying 4, ensuring to use four different colors of mana.
2. Lux Artillery triggers, giving Crystalline Crawler sunburst, causing it to enter with eight +1/+1 counters due to sunburst and its converge ability.
3. Activate Crystalline Crawler's first ability eight times by removing eight +1/+1 counters from it, adding 4.
4. Activate Meticulous Excavation by paying 2, returning Crystalline Crawler from the battlefield to your hand.
5. Repeat.

This loop is a masterclass in converting color-filtered mana and card recycling into an infinite engine, powered entirely by the synergy between your board pieces. When you cast Crystalline Crawler, Lux Artillery grants it sunburst, which stacks with its native converge ability to load it up with eight total +1/+1 counters when paid for with four distinct colors. You then tap into Crystalline Crawler's ability to strip those counters away for a massive mana windfall, which easily funds Meticulous Excavation's activation cost to bounce Crystalline Crawler right back to your hand. Because Meticulous Excavation lets you loop this entire casting process on your turn, you can repeat it endlessly to generate infinite mana, storm count, and artifact or creature triggers.
