Okay, so the general consensus is that the card is overpowered.
Personally find it a bit too game changing. Not all Rainbows use reflective shields,
Well, most rainbows use steal or destroy. Which is another effective counter against this card.
So i'm nerfing the card as follows:
Changing cost from 4
to 4
Adding ability, costs 2
My reasoning is that, Darkness/Entropy already have Lycanthrope/Werewolf, so this adds another synergy.
Now, when you play the card, it has to sit idle for one turn before you can activate it's ability. In my opinion this makes it underpowered, and very vulnerable to steals/destroys. But, I guess from the criticism so far, does balance it more.
edit: Just found a new problem with the way it works now.
When you activate it's ability, the card should be destroyed? But, for your opponent to take damage as he gains quanta, the card has to remain in play until at least the end of his turn. So, the problem I can see this creating, is for an AI to Deflagrate an activated Quantum Bleeding card (or, more successfully, stealing an already activated one to affect your opponent) - but this gives us the problem of when to remove the card... I honestly think the earlier version was simpler
.
Your thoughts are welcome.
