Wall of Roots + Agatha's Soul Cauldron + Tayam, Luminous Enigma + Phyrexian Altar + Vizier of the Scorpion

Wall of Roots

Agatha's Soul Cauldron

Tayam, Luminous Enigma

Phyrexian Altar

Vizier of the Scorpion

How it works

1. Cast Vizier of the Scorpion by paying its mana cost; it enters with a vigilance counter due to Tayam.
2. When Vizier of the Scorpion enters, it triggers, creating a 0/0 creature token with a +1/+1 counter on it as well as a vigilance counter due to Tayam.
3. Declare that you are activating Tayam's ability, so state-based actions will not be checked until the ability is activated.
4. While paying that ability's cost, activate the creature token using the Wall of Roots mana ability from Agatha's Soul Cauldron by putting a -0/-1 counter on it, adding .
5. Complete the activation by paying 3 and removing a vigilance counter from each of the two creatures and a -0/-1 counter from the Army token.
6. Holding priority, activate Phyrexian Altar twice by sacrificing Vizier of the Scorpion and the creature token, adding two mana.
7. Resolve Tayam's ability, milling three and returning Vizier of the Scorpion from your graveyard to the battlefield with a vigilance counter on it.
8. Repeat from step 2.
