You mulligan for these, they are your early drops and activators for synergies. Only keep twilight's call if you have loat hoarders and/or gilded gargoyles. Allways keep dragonsoul against any non aggro deck.
This deck has multiple win conditions, from tons of 5/5 dragons, to pushing out a ton of 0 mana 8/8’s and 7/8’s (extra copies with seance) and widdeling your opponent down with shadowreaper anduin, this deck is a blast to play. Wild pyromancer can give you some nice board clears vs swarmy decks while potentialy developing a 5/5 or two. Your main goals are to hit two gilded gargoyles and/or loat hoarders and rez them with twilight’s call, it will give you alot of cheap spells for dragonsoul or shadowreaper. Priest of the feast can also heal you a ton in a pinch.
