Invasion of Amonkhet // Lazotep Convert + Ojer Kaslem, Deepest Growth // Temple of Cultivation + Phyrexian Altar

Invasion of Amonkhet // Lazotep Convert

Ojer Kaslem, Deepest Growth // Temple of Cultivation

Phyrexian Altar

How it works

1. Defeat Invasion of Amonkhet
2. Invasion of Amonkhet triggers, causing you to exile it, and return it to the battlefield transformed as Lazotep Convert.
3. Choose to have Lazotep Convert enter the battlefield as a copy of Ojer Kaslem that is a 4/4 Zombie.
4. Activate Phyrexian Altar by sacrificing Lazotep Convert, adding one mana of any color.
5. When Lazotep Convert dies, it triggers, causing you to exile it, and return it to the battlefield transformed as Lazotep Convert.
6. Choose to have Lazotep Convert enter the battlefield as a copy of Ojer Kaslem that is a 4/4 Zombie.
7. Repeat from step 4.

This ingenious loop turns a clever clone interaction into an endless engine by leveraging the unique properties of double-faced cards in the graveyard. Once you defeat Invasion of Amonkhet and cast it transformed as Lazotep Convert, it enters as a copy of Ojer Kaslem, Deepest Growth (which somehow ends up in the graveyard to be copied). Because Phyrexian Altar is waiting on the battlefield to sacrifice your newly minted Ojer Kaslem clone for any color of mana, the resulting death triggers send the card back to the command zone or exile-and-transform state that lets you repeat the process endlessly. Temple of Cultivation quietly waits on the reverse side of the equation, but it's the recursive copying of Ojer Kaslem fueled by the Altar's sacrifice outlet that keeps the infinite mana and entry triggers flowing.
