Commander decks love this card as a combo engine, and it even has a sneaky alt-win with its sacrifice 10 permanents ability
There are 6 rares and 1 mythic rare in the borderless frame break treatment (0.8% in total), 2 rares and 2 mythic rares in the borderless profile treatment (0.3% in total), 2 rares and 1 mythic rare in a retro frame (0.2% in total), and 1 additional borderless mythic rare (less than 0.1%)
To support these new cards I added some extra Eldrazi to the cube and also Borborygmos Enraged who is actually the third best legend for the job despite being pretty naff compared with other cards of his cost
The condition is determined by a variety of conditions, and the main way to judge it is a combination of the number of markings and how many there are on the card
Because damage remains marked on a creature until the damage is removed as the turn ends, nonlethal damage dealt to Champion of the Flame may become lethal if an Aura or Equipment attached to it leaves the battlefield or becomes attached to another creature during that turn
