Hollowhenge Overlord + Parallel Lives + Elspeth, Storm Slayer

Hollowhenge Overlord

Parallel Lives

Elspeth, Storm Slayer

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 Parallel Lives and Elspeth, Storm Slayer.
2. Repeat step 1 during each of your upkeeps. You'll create exponentially more Wolves each time assuming the Wolf tokens survive.

This loop turns a single Wolf or Werewolf into an exponential tidal wave of fangs during every upkeep, fueled entirely by Hollowhenge Overlord's triggered ability. What makes this pack grow out of control so rapidly is the relentless multiplication power of Parallel Lives and Elspeth, Storm Slayer, both of which double your token generation. Because these replacement effects stack multiplicatively, a single upkeep trigger instantly quadruples your pack size, letting you overwhelm opponents with near-infinite creature tokens and endless enter-the-battlefield triggers before they can even blink.
