A lot of us say that Rewind is OP. But look at Lighting. This card can kill 70% creatures or more... Rewind didn't kill, but You lose one draw from deck. I think that it is balanced. If we talk about nerf Rewind we must nerf Lighting - and then I will agree with You
Lighting and Rewind for 2 quantum, Shockwave for 1 (because there are a lot of creatures with 5HP and this card is less useful than Lighting).
I would like see this changes in Trainer. We seriously must talk about balance in game and I think that this topic is good place to do it. Now in game we have too much OP cards like Antimatter, BlackHole, FireLance, RageElixir and much more. And on the opposite a lot of stupid and not useful cards like HolyLight, Mercenary etc.
I never understood why Egg has got 0/1 stats and Ash 0/7 (now 0/5). I agree that Ash must have 0/1 stats. There are a lot of non balanced facts and my favourite is with FireLance.
Fire Lance cost 1, deals 3 damage and it is good when we compare it with DrainLife. But IceBolt also cost 1 and gives only 2 damage and sometimes congeal. Sorry, but it isn't fair. 1 damage for 10 quantum is a huge difference. FireLance kill 90% creatures with 10 quantum, IceBolt kill maybe half of them.
So what is the sense of congeal from IceBolt, when FireLance destroy creature?Shield reduce 1 damage and cost 1. Tower shield reduce 2 and cost 5! Acceleration gives 2/1 and cost 3. Overdrive cost more and it is upped card because it gives 1 attack more! And the same MUST be with FireLance. It gives 1 damage more so it MUST cost 2 or maybe 3, but not 1.
FireLance should cost 4/3 or 3/2 (we can discuss here), Drain Life 3/2, IceBolt 2/1. Then it will be better balanced. Sorry, but it is truth...
