Death's Presence + Ashnod's Altar + Spike Breeder

Death's Presence

Ashnod's Altar

Spike Breeder

How it works

1. Activate Spike Breeder's second ability by paying 2 and removing a +1/+1 counter from it, creating a 1/1 Spike creature token.
2. Activate Ashnod's Altar by sacrificing the Spike, adding CC.
3. When the Spike dies, Death's Presence triggers, putting a +1/+1 counter on Spike Breeder.
4. Repeat.
