Shaile, Dean of Radiance // Embrose, Dean of Shadow + Crystalline Crawler + Cryptic Trilobite + Sword of the Paruns

Shaile, Dean of Radiance // Embrose, Dean of Shadow

Crystalline Crawler

Cryptic Trilobite

Sword of the Paruns

How it works

1. Cast Crystalline Crawler by paying 4.
2. Cast Cryptic Trilobite by paying 2.
3. Activate Shaile by tapping it, putting a +1/+1 counter on Crystalline Crawler, Cryptic Trilobite and any other creature that entered the battlefield under your control this turn.
4. Activate Crystalline Crawler's first ability by removing a +1/+1 counter from it, adding .
5. Activate Cryptic Trilobite's first ability by removing a +1/+1 counter from it, adding CC that can only be spent to activate abilities.
6. Activate Sword of the Paruns by paying 3, untapping Shaile.
7. Repeat from step 3.

This clever loop harnesses the synergy between growth and activation costs to generate infinite +1/+1 counters on your team. You use Shaile, Dean of Radiance // Embrose, Dean of Shadow to constantly refresh your board with +1/+1 counters, which Crystalline Crawler and Cryptic Trilobite then happily consume for mana. That generated mana pays to untap Shaile, Dean of Radiance // Embrose, Dean of Shadow using Sword of the Paruns, allowing you to repeat the process indefinitely.
