Yes certainly! I like your conditional no normal draw version quite a bit. I’d probably have to see them in action to decide which I prefer.
I think making PCP cost two cards nerfs “topdeck hero” DeGrey playstyles without really bothering more conservative playstyles. The smaller a player’s hand, the more it hurts to have to discard and the more likely they are to have to discard something valuable. If 7 cost two cards to discard, topdeck hero DeGrey would be weaker because 7 would be a much less real threat from a small hand, while DeGreys that build hand more are rewarded by being able to realistically threaten 7 flips.
As a real example, I was recently playing a game against Leontes in which I had AA and 1 random card after dumping most of my hand to bring him to ~30 life and powering up. I topdecked a 7, beat his FDB/dodge mixup by spending my 1 low value card to flip 7, and confirmed into AA for lethal. This wouldn’t be possible if PCP cost two cards to flip.
