Hollowhenge Overlord + Adrix and Nev, Twincasters + Parallel Lives

Hollowhenge Overlord

Adrix and Nev, Twincasters

Parallel Lives

How it works

1. At the beginning of your upkeep, Hollowhenge Overlord triggers, creating four 2/2 Wolf creature tokens for each Wolf and/or Werewolf you control due to Adrix and Nev and Parallel Lives.
2. Repeat step 1 during each of your upkeeps. You'll create exponentially more Wolves each time assuming the Wolf tokens survive.
