But people seem to forget that the heal is the only thing keeping this card from being extremly situational.
I don't believe the last War to be situational. But I wasn't there, so you might want to ask a war veteran what they think about it.
The problem is that it'd turn to be too situational (see purify, it's underused).
If you add a timer you'll lose its use in stalls, that are the decks that will mostly use this.
Rushes don't suffer from quanta denial by itself, they suffer from CC (is not the same Pestal than Pestal+Siphons/Lightings).
See above. I don't believe this is supposed to stop things like
Pestal, that's a fine deck. But Discord? Hell yeah. Dark Matter? That, also, but I don't believe CCYB really needs more help...
Anyway, I digress. Stalls won't use it with a timer? Of course they will. Dark Matter is an autoquit for rainbows now. When this is out, they can use it, and even with a timer, 5 turns of being safe from BHs mean you can definitely get your field laid out, and have a chance. Not the perfect counter you expected? Yeah, but let me ask you this: is BH a perfect counter to Rainbows? If so, why the hell should rainbows have a perfect counter to their perfect counter? A small counter would work, but I don't think they NEED more help, really.
Rushes suffer from denial as well, try USEM against a Discord + BH and we'll see how that goes.
And Discord is the problem. With a low cost and a timer, you solve that problem. Without a low cost, you probably don't.
