Devoted Druid + Leyline of Abundance + Conclave Mentor + Doc Samson, Super Psychiatrist

Devoted Druid

Leyline of Abundance

Conclave Mentor

Doc Samson, Super Psychiatrist

How it works

1. Activate Leyline of Abundance by paying 6, putting four +1/+1 counters on each creature you control due to Doc Samson and Conclave Mentor.
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 magnificent loop turns Devoted Druid into a self-sustaining mana engine by leaning on multiple replacement effects to grow your creatures out of control. When you tap Devoted Druid for mana and untap it using its own -1/-1 counter ability, Leyline of Abundance steps in to double your green production while fueling the grand activation that kicks off the loop. To keep the Druid from perishing to its own counters, Conclave Mentor and Doc Samson, Super Psychiatrist work together to massively amplify every +1/+1 counter placed by Leyline of Abundance's hefty ability, completely erasing the -1/-1 counters and leaving your board infinitely larger and richer in green mana than before.
