How it works

1. Activate Leyline of Abundance by paying 6, putting four +1/+1 counters on each creature you control due to Loading Zone 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 engine turns Devoted Druid's self-inflicted `-1/-1` counters into an absolute engine of growth, using Loading Zone and High Score to exponentially multiply every counter that lands on your board. As the Druid taps and untaps to generate massive green mana, Leyline of Abundance kicks in to double your mana production while providing the heavy-duty mana sink needed to kick off the counter-producing loop. Once activated, Loading Zone doubles the counters you receive and High Score tacks on an extra one for good measure, completely overwhelming the Druid's drawback and leaving you with an unstoppable army bearing infinite `+1/+1` counters.
