Devoted Druid + Leyline of Abundance + Benevolent Hydra + Doubling Season

Devoted Druid

Leyline of Abundance

Benevolent Hydra

Doubling Season

How it works

1. Activate Leyline of Abundance by paying 6, putting four +1/+1 counters on each creature you control due to Doubling Season and Benevolent Hydra.
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 setup turns a humble mana-producer into an engine for boundless growth by letting its own self-correction fuel an ever-escalating loop. Devoted Druid normally balances its ability to untap by accumulating -1/-1 counters, but Leyline of Abundance supercharges your green mana production to fund a massive board-buffing ability. Meanwhile, Doubling Season and Benevolent Hydra work in tandem as exponential counters multipliers, turning a modest investment into an overwhelming cascade of +1/+1 counters that cancels out the Druid's drawbacks and leaves your entire army infinitely large.
