I was quite perplexed by this... I played a seraph, and (I was playing a nova/immolation deck, shut up) used a quintessence on a seraph. The next turn, I used the ability since hell, why not. Turns out it just removed it when it was done... is that supposed to be on purpose? I know its kinda my fault, but really? (and none of the cards in that deck use light quanta, shut up... lol)
