Hollowhenge Overlord + Adrix and Nev, Twincasters + Anointed Procession

Hollowhenge Overlord

Adrix and Nev, Twincasters

Anointed Procession

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 Anointed Procession.
2. Repeat step 1 during each of your upkeeps. You'll create exponentially more Wolves each time assuming the Wolf tokens survive.
