Tip for speeding up Miracle

[Zeru]

He'll cast Miracle as soon as the green part of his health bar is lower than 12 HP.
green part = (current HP) - (estimated damage in yellow)

Is this really true? I always thought that the AI uses miracle whenever the "timer of death"=2. It could be 12 estimated hp, but it could be 40.
Maybe your deck doesn't deal enough dmg.

It was true at the time CK posted that. It's most likely something similar now as well, if not exactly the same.

[Nadrin]

Miracle will also use Miracle if his/her health is lower than 110 OR the green bar is less than 12.

yeah usually I just keep a bunch of high hitters in my hand, if I can keep my HP up until then. and when he has like 50 left, he doesn't heal until it goes close to single digits or if the estimated damage matches the current. and Ill have like 100 quanta by this time, then just spam the high hitters and umm..hes dead.

Usually I'm dead before that though XD

If you're facing him with ROL/Hope deck you should fractal dragons at the last minute and kill him. Or if you're dealing 100+damage already just wait until he uses all of his miracles
