If you use EB's just add an improved heal. Bonds will help keep you alive, along with SoG's if you use them, and then heal on the turn you will kill your opponent for the EM
I don't think you understand why the change is a problem for many decks.
The basic strategy I had been using was something like this:
-Early stalling with LOTS of SoD's & some bonds
-Build up to the kill (by mutating the tiny critters I summoned to feed the bond, if it matters)
-Miracle on the last turn to EM with 180-220 hp, rake in cash
It wasn't super fast, but with EM's at twice the normal hp it was still a pretty effective grinding deck. What's more, it was the ONLY grinding deck I have ever found that was not another rush deck.
And sadly, some of us find rush decks pretty boring to play.
As to your suggestion, yes it is still
technically possible to get EMs with the miracle & heal combo, but it really does not work in this strategy because:
-You can't both stall hard early on and get the EM. If you use heal to stall early then the miracle combo doesn't work.
-It requires 2 "dead cards" in the hand instead of 1
-You need to draw both miracle and heal to get the EM, which makes it much less likely.
