Mulligans
Muligan hard for elemental allies, having it in opening hand significantly improves this decks success rate, if you are only drawing (mostly)mid range elementals with you’re spells already in hand you can deal with a lot with this deck. the Aim is to make use of elemental evocation, cosmic anomaly, fireball and frost bolt to do big face damage in a big burst. celestial emissary adds this similar burst capability for a single spell, which is fine as we dont have many spells.
personally i always keep an arcane amplifier if i get one in muligan, in fact id happily elemental evocation it out turn one for 5 damage turn 2 even playing it turn 3 alone as a 2/5 is hard to get off board for 3 mana. firehawk is a threat early on too
i like to run a conjurer’s calling for getting some extra value out of late game board presence after having to trade into the opposition.
Sorcerer’s apprentice is only of limited value for most plays with this deck. Its so heavily targeted when played it can actually keep other more valuable cards alive, i see no benefit to more than one in this deck.
more expensive cards of interest to add to this deck would be khadgar, for the triple animated avalanche, and jan’alai the firehawk (spelling) because arcane amplifier can rapidly speed up the process of summoning a ragnaros, it can be done almost passively. likewise I do run a siamat and mana giant at the moment but mana giant isn’t actually so strong in this deck it is very situational with the mana cyclone, and likewise chenvaala isnt a very good synergy for our mid/higher cost spells.
