Champion of Irum vs DMT

[5tumbl]

My opponent had a champion at one health.. I summon a death mage and direct the damage point on the champion.
Yet, he takes the bonus HP before the damage...

It's not clear at which point the DMT becomes an opposite ally, but it would seem more logical after thesummoning is complete, i.e. After the little Irum bugger is dead, wouldn't it ?

Heya,

Champion of Irum is unique in that it is not a triggered ability. Rather, it is a passive ability that is always recalculating his attack/health bonus based on how many opposing allies of cost 3cc or higher are in play. The reason Death Mage Thaddeus can't kill a 1 health Champ is because his ability doesn't trigger until he is summoned, but the moment he is summoned is when Champion of Irum's passive ability will passively calculate the +1/+1 bonus. It will essentially look like (1+1)-1 = 1

Hope that helps
