Wall of Roots + Agatha's Soul Cauldron + Tayam, Luminous Enigma + Lazotep Reaver + Phyrexian Altar

Wall of Roots

Agatha's Soul Cauldron

Tayam, Luminous Enigma

Lazotep Reaver

Phyrexian Altar

How it works

1. Cast Lazotep Reaver by paying its mana cost; it enters with a vigilance counter due to Tayam.
2. When Lazotep Reaver 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 Lazotep Reaver and the creature token, adding two mana.
7. Resolve Tayam's ability, milling three and returning Lazotep Reaver from your graveyard to the battlefield with a vigilance counter on it.
8. Repeat from step 2.
