'Bloodwing Angel · Oservie', 8/9, 'Magic Resistance', when it enters the battlefield, transforms it into 'Purple Flame Sea', non-'Demon' 'Dragon' attribute minions take 3 damage upon entry and get -2/-2, field lasts for 3 turns. (This angel, returned from Hell, is no longer the initial light of dawn)
'Magic Resistance' means that she cannot be targeted by spell cards, and close combat damage is further limited by the field, which is extremely restrictive for Purple Lightning Lala, whose deck is largely made up of low-cost knights for rapid assaults.
[Things are not looking good; Purple Lightning Lala is in trouble now.]

[We can only hope for Miss Dantalion now.]
Sure enough, after some thought, Clara reluctantly chose to pass, leaving this turn empty, because any minion she summoned would be burned alive upon entry.
