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 Branching Evolution 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.

This clever engine transforms Devoted Druid from a simple mana dork into an unstoppable counter factory by continuously washing away its self-inflicted penalties. The trick relies on Leyline of Abundance doubling up your green mana production while actively fueling the massive investment needed to pump up your board. Meanwhile, Branching Evolution and High Score work in tandem as multiplicative modifiers, taking the base investment from Leyline's activated ability and exponentially amplifying it into a torrent of growth. By alternating between tapping for extra green mana and resetting its state, the druid effortlessly powers the loop while the counters accumulate infinitely.
