Devoted Druid + Leyline of Abundance + Hardened Scales + Doc Samson, Super Psychiatrist

Devoted Druid

Leyline of Abundance

Hardened Scales

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 Hardened Scales.
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 intricate loop transforms a humble druid into an engine of limitless growth by leaning heavily on overlapping replacement effects. While you tap and untap Devoted Druid to generate green mana—with Leyline of Abundance doubling each of those mana productions—the core breakthrough happens when you activate Leyline of Abundance's massive mana sink ability. Instead of just adding a modest number of markers, Hardened Scales and Doc Samson, Super Psychiatrist act in concert to dramatically amplify every counter that gets placed, ensuring that a single activation leaves your entire board with astronomical power and toughness.
