I wouldn't say it's overpowered because it does the same thing dim shield does, but in a different way, and it's effective still in pvp2. That's the only bonus to it compared to dim shield in pvp2. It's a spell card that cost 1 random quantum like animate weapon that sacrifices 1 HP, gives you 1 HP, (you as in the caster) and gives you 1 random quantum. May be played multiple times in one turn like relic. How is this like dimensional shield? They both make pvp1's rage quit. But it also works in pvp2, just less effectively because pvp2 is where people have spent hours playing the game and probably have more patience.
BrandenC's Bravery is the upped version of it. This card is much like Higurashi, but she's way too overpowered, so I thought for a more balanced idea. You better be one brave person to play this though, cause it requires 100 quanta! If you can get 100 quanta without using novas or immolations, then congrats sir, you can be my trusty side kick in matches. I'd take a brave soul like yours to any gun fight, provided you have a knife of course. That way your not OP like Hig's. Its a spell card too, and has the ability "Medal of Valor" which wins you the game instantly!
It also acts like spell damage (Bold part @Higurashi.) that way you win the game 1 turn earlier then what you were suppose to.
