Quandrix Command + Crystalline Crawler + Naru Meha, Master Wizard + Innkeeper's Talent

Quandrix Command

Crystalline Crawler

Naru Meha, Master Wizard

Innkeeper's Talent

How it works

1. Cast Quandrix Command by paying its mana cost, choosing its first and third modes.
2. Holding priority, cast Naru Meha by paying its mana cost.
3. When Naru Meha enters, it triggers, copying Quandrix Command, with the copy's first mode targeting Naru Meha and the copy's third mode targeting Crystalline Crawler.
4. Resolve the copy of Quandrix Command, returning Naru Meha from the battlefield to your hand and putting four +1/+1 counters on Crystalline Crawler due to Innkeeper's Talent.
5. Holding priority, activate Crystalline Crawler three times by removing four +1/+1 counters from it, adding 2.
6. Repeat from step 2.

This clever loop relies on Naru Meha, Master Wizard to endlessly copy Quandrix Command, bouncing Naru Meha back to your hand while simultaneously feeding Crystalline Crawler the exact mana and counters it needs to keep the chain going. Every time Crystalline Crawler receives its new counters, Innkeeper's Talent doubles the influx due to its Level 3 ability, leaving plenty of leftover energy to strip away for the required blue mana. Meanwhile, the static protection from Innkeeper's Talent's Level 2 ability even helps safeguard your key permanents from targeted disruption while you execute the infinite sequence.
