Wall of Roots + Agatha's Soul Cauldron + Tayam, Luminous Enigma + Phyrexian Altar + Easterling Vanguard

Wall of Roots

Agatha's Soul Cauldron

Tayam, Luminous Enigma

Phyrexian Altar

Easterling Vanguard

How it works

1. Activate Phyrexian Altar by sacrificing Easterling Vanguard, adding mana.
2. When Easterling Vanguard dies, 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. Activate [[Tayam]] by paying 3 and removing three counters from creatures you control, milling three cards and returning Easterling Vanguard from your graveyard to the battlefield with a vigilance counter on it.
4. Declare that you are activating Tayam's ability again, so state-based actions will not be checked until the ability is activated.
5. 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 .
6. Complete the activation by paying 3 and removing a vigilance counter and a -0/-1 counter from the creature token and a vigilance counter from Easterling Vanguard.
7. Holding priority, activate Phyrexian Altar twice by sacrificing Easterling Vanguard and the creature token, adding mana.
8. When Easterling Vanguard dies, it triggers, creating a 0/0 creature token with a +1/+1 counter on it as well as a vigilance counter due to Tayam.
9. Resolve Tayam's ability, milling three cards and returning Easterling Vanguard from your graveyard to the battlefield with a vigilance counter on it.
10. Repeat from step 4.
