Reply to Delwynn Dragonscale - NEW Dragon Summoner with +1 Magic Attack - Too Expensive with 5 Mana?
I think its important to note that the new dragon promo summoner is a Common card so it can't be as good as a rare summoner.
The current rare dragon summoner cost 4 Mana and has one buff. It makes sense to me that the common summoner would cost 5 Mana with a buff. If the mana was to go any lower then the buff would need to be removed as to keep the order of things in place (common< Rare < Epic < Legendary)
