I actually forgot about Overpower when thinking of this concept. In a world with no overpower, I thought it might be interesting; now that I remember Overpower exists, I feel the concept is much worse than I initially imagined. Oh, well.
I was trying to make a Frenzy card whose use would be primarily to pump other frenzy cards, allowing for a secondary use if you were willing to discard frenzy cards. I'm not sure how to save the concept now that you've reminded me of overpower.
