MTG Combo: Deathbringer Thoctar + Heliod, Sun-Crowned
With both on the battlefield, Heliod does not need to be a creature, activate Heliod's ability to grant Deathbringer Thoctar lifelink. Then, activate Deathbringer Thoctar to remove a +1/+1 counter on it when it gets one to deal damage. Lifelink happens, and Heliod's passive triggers, targeting Deathbringer Thoctar and putting a +1/+1 counter on it, which you can then remove again, and the combo results in infinite damage.
