Devoted Druid + Leyline of Abundance + The Earth Crystal + High Score

Devoted Druid

Leyline of Abundance

The Earth Crystal

High Score

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 High Score.
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 ingenious green loop relies on a clever interplay of counters to turn ordinary mana production into an explosive growth engine. While Devoted Druid normally destroys itself under the weight of its own -1/-1 counters, Leyline of Abundance steps in to double your green mana while its hefty activation cost acts as the ultimate outlet. The real magic happens because The Earth Crystal and High Score create a compounding replacement effect: whenever counters are placed, these two passive powerhouses multiply and add to the total, turning a modest counter activation into an overwhelming cascade of four +1/+1 counters that instantly wipe away the Druid's self-inflicted penalties and allow the whole cycle to repeat indefinitely.
