How it works
Activate Antler Skulkin by paying 2, giving Phantom Nishoba persist until end of turn.
Activate Ashnod's Altar by sacrificing Phantom Nishoba, adding CC.
When Phantom Nishoba dies, its persist ability triggers, returning it to the battlefield from your graveyard with six +1/+1 counters on it due to its first ability.
