Checked some of them out, and reason why this is so good is obvious:
OP cards are OP
Really, Fire has one of the best CC and PC. Fire shield ? Are they serious ? Damaging ALL
creatures that ever will hit the field. Totally OP - same goes to Sanctuary's stacking heal
effect. Using it in my rainbow control deck two times because of his OPness, too
Won't say anything about miracle, that's really obvious.
But, i don't think its such of a deal, it's a control deck without hourglass. Thats its weakness,
at least rainbow decks have a good chance against it. They run the necessary PC (steal, deflag)
and are faster in drawing cards trough hourglass.
So to counter this deck IMO you just have to run more PC, its overall good anyways. The only Problem is that some Elements just dont have good options for PC, which is unfair, because Pc is very powerful in this game as long as you dont play stupid "i just get much damage on the field and roxxxorrz this game!!11!!".
Just my opinion, no hate pls
