Soul Diviner + Patchwork Crawler + Devoted Druid

Soul Diviner

Patchwork Crawler

Devoted Druid

How it works

1. Activate Patchwork Crawler using Devoted Druid's second ability by putting a -1/-1 counter on it, untapping it.
2. Activate Patchwork Crawler using Soul Diviner's ability by tapping it and removing a -1/-1 counter from it, causing you to draw a card.
3. Repeat.

This clever loop turns Devoted Druid's self-inflicted drawback into pure, cycling fuel by feeding its abilities straight into Patchwork Crawler. Because the Crawler gains the activated abilities of every creature exiled with it, it can absorb the Druid's untap ability—complete with its cost of putting a -1/-1 counter on itself—alongside Soul Diviner's capacity to convert that very same counter into a fresh card. Tapping the Crawler to draw while simultaneously scrubbing away the counter with Soul Diviner lets you repeat this untap-and-draw cycle endlessly.
