Tayam, Luminous Enigma + Sengir, the Dark Baron + Ashnod's Altar + Young Wolf

Tayam, Luminous Enigma

Sengir, the Dark Baron

Ashnod's Altar

Young Wolf

How it works

1. Activate Ashnod's Altar by sacrificing Young Wolf, adding CC.
2. When Young Wolf dies, its undying ability and Sengir's first ability trigger.
3. Resolve the Young Wolf trigger, returning it from your graveyard to the battlefield with a +1/+1 counter and a vigilance counter on it.
4. Resolve the Sengir trigger, putting two +1/+1 counters on Sengir.
5. Activate Tayam by paying 3, removing a +1/+1 counter from Sengir, and both counters from Young Wolf.
6. Holding priority, activate Ashnod's Altar by sacrificing Young Wolf, adding CC.
7. Repeat steps 2-4 one additional time.
8. Activate Ashnod's Altar by sacrificing Young Wolf, adding CC.
9. Resolve Tayam's ability from step 5, causing you to mill three cards and returning Young Wolf from your graveyard to the battlefield.
10. Repeat.

This loop is a masterclass in recycling resources, anchored by the sacrifice engine of Ashnod's Altar to turn Young Wolf's endless demise into raw colorless mana. Because Tayam, Luminous Enigma bestows a vigilance counter upon entry, and Young Wolf returns with an undying counter, you have a ready supply of counters to feed Tayam's ability and consistently dig the wolf back out of your graveyard. Meanwhile, every sacrifice fuels Sengir, the Dark Baron, growing him to astronomical proportions as the loop repeats.
