Devoted Druid + Leyline of Abundance + Branching Evolution + Winding Constrictor
How it works
- Activate Leyline of Abundance by paying 6, putting four +1/+1 counters on each creature you control due to Winding Constrictor and Branching Evolution.
- Activate Devoted Druid's first ability by tapping it, adding .
- Leyline of Abundance triggers, adding .
- Activate Devoted Druid's second ability by putting a -1/-1 counter on it, untapping Devoted Druid.
- Repeat from step 2 three additional times.
- Repeat from step 1.
This dazzling loop transforms Devoted Druid from a humble mana-producer into an engine of endless growth by leaning entirely on replacement effects. While you tap the Druid and place its self-inflicted -1/-1 counters to untap it repeatedly, Leyline of Abundance ensures that every tap generates an extra green mana alongside a massive windfall of green mana. The real magic happens when you pump those resources into Leyline of Abundance's activated ability; thanks to the compounding replacement effects of both Branching Evolution and Winding Constrictor, a single activation snowballs into four +1/+1 counters on each of your creatures. By alternating between generating mana and exponentially multiplying your counters, you can easily repeat the process to grow your board infinitely large.
