Ashaya, Soul of the Wild + Phyrexian Altar + Badgermole Cub

Ashaya, Soul of the Wild

Phyrexian Altar

Badgermole Cub

How it works

1. Cast Badgermole Cub by paying its mana cost
2. When Badgermole Cub enters, its earthbend ability triggers, causing it to earthbend itself as it is a Forest due to Ashaya.
3. Activate Phyrexian Altar by sacrificing Badgermole Cub
4. When Badgermole Cub dies, it triggers, returning itself from your graveyard to the battlefield tapped.
5. When Badgermole Cub enters, its earthbend ability triggers, causing it to earthbend itself as it is a Forest due to Ashaya.
6. Repeat from step 3.
