The 2/5 reborn taunt will kill warrior if paladin can keeps copying it. The 2/5 reborn+copy is not that easy to clear if you already have to safe your brawls and aoe execute for the eggs and mech dragon (which are not cleared by brawl btw,but maybe spellbreaker). Even the 1/2 2 mana reborn will overwhelm the warrior if he can not clear it fully and paladin can keep copying. Then there is the 6 mana 3/4 reborn and then things come back with undertaker and army as well.
This deck will be heavily complained about by control players as soon as it becomes stronger in the meta. It has much more value then boom will ever give.
The focus of the pro,s is on boom and mage. So I guess that means that the pros think all the other mechanics and decks in the game are currently fine. I don’t expect any complaints from the pros in the future about any of the current decks that are not warrior and mage. If they have any complaints then now is the time to come forward,not in 4 or 8 months when a new expansion hits.
