Devoted Druid + Leyline of Abundance + Vorinclex, Monstrous Raider + Hardened Scales

Devoted Druid

Leyline of Abundance

Vorinclex, Monstrous Raider

Hardened Scales

How it works

1. Activate Leyline of Abundance by paying 6, putting four +1/+1 counters on each creature you control due to Hardened Scales and Vorinclex.
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 clever loop relies on Devoted Druid's ability to untap itself by placing a -1/-1 counter, which normally limits its own longevity, but Vorinclex, Monstrous Raider and Hardened Scales completely rewrite the math of the battlefield. Because Vorinclex doubles counters and Hardened Scales adds an extra +1/+1 counter to the mix, you can use Leyline of Abundance's expensive activation to drop an overwhelming number of +1/+1 counters onto your creatures, instantly erasing any accumulation of -1/-1 counters and permanently growing your board. With those same mana-doubling effects from Leyline of Abundance backing up Devoted Druid's taps, you generate a massive surplus of green mana while pumping out infinite +1/+1 counters on your creatures.
