Devoted Druid + Leyline of Abundance + Vorinclex, Monstrous Raider + The Earth Crystal

Devoted Druid

Leyline of Abundance

Vorinclex, Monstrous Raider

The Earth Crystal

How it works

1. Activate Leyline of Abundance by paying 6, putting four +1/+1 counters on each creature you control due to The Earth Crystal and Vorinclex.
2. Activate Devoted Druid's first ability by tapping it, adding .
3. Leyline of Abundance triggers, adding .
4. Activate Devoted Druid's second ability by putting a -1/-1 counter on it, untapping Devoted Druid.
5. Repeat from step 2 three additional times.
6. Repeat from step 1.

This clever loop turns Devoted Druid's self-untapping mechanic into a massive engine by cycling its own downside away. Ordinarily, the druid would eventually perish from its own -1/-1 counters, but Vorinclex, Monstrous Raider and The Earth Crystal team up to generously double every +1/+1 counter from Leyline of Abundance's activated ability into a towering pile of stats that effortlessly cancels out the penalties. As you repeatedly tap the druid for mana—doubled by Leyline of Abundance's mana-boosting static ability—you generate a staggering surplus of green mana to fuel the loop infinitely.
