There have been five new cards spoiled over the weekend. This article covers Demented Frostcaller, Shifting Shade, and Twilight Flamecaller. These three cards bring the total number of cards covered so far to sixty eight, which takes us over the halfway point.
Demented Frostcaller is yet another card that will be hard to assess until it is placed in the new meta. The tempo gain from the card will often be good. It might well function in a tempo deck in a similar manner to how currently functions in Druid. It has also been confirmed that it will try to freeze a currently non-frozen target.
Shifting Shade is a decent, but uninspiring looking card advantage card for Priest. The acid test of whether this will be playable or not will likely be the number of 3-power minions and damage spells in the meta. If it dies too easily, the extra card will likely not make up for the four mana outlay.
Twilight Flamecaller seems to be an upgraded . It is probably too situational to be included in the first decks to be tried in the new metagame.Shadowcaster and Forlorn Stalker .Servant of Yogg-Saron and Faceless Summoner .Deathwing - Dragonlord and Embrace the Shadow .Thistle Tea and Twilight Summoner .Wisps of the Old Gods and Soggoth the Slitherer .Cho'Gall and Possessed Villager .Yogg-Saron and Spreading Madness, plus lore .
