Antler Skulkin + Ashnod's Altar + Arcbound Shikari

Antler Skulkin

Ashnod's Altar

Arcbound Shikari

How it works

1. Activate Antler Skulkin by paying 2, giving Arcbound Shikari persist until end of turn.
2. Activate Ashnod's Altar by sacrificing Arcbound Shikari, adding CC.
3. When Arcbound Shikari dies, its modular and persist abilities trigger.
4. Resolve the modular trigger, putting all +1/+1 counters on Arcbound Shikari onto another artifact creature you control.
5. Resolve the persist trigger, returning Arcbound Shikari from your graveyard to the battlefield with one +1/+1 counter on it due to its modular ability.
6. When Arcbound Shikari enters the battlefield, it triggers, putting a +1/+1 counter on each other artifact creature you control.
7. Repeat.
