Just giving 2 ideas to make Black deck less of a pain to play as:
1. Start run with Hieroglyph and Blank (instead of -1 hand +1 joker slot)
This method makes early game not as bad as current black deck cuz you have a whole extra ante 0 to buffer your start, tradeoff being the +1 joker slot is only half obtained through the mechanic of step 1 to antimatter.
2. Instead of -1 hand +1 joker slot at start of run, Black deck gain -1 hand +1 joker slot every 4 times ante increases.
This delays the problem the condition creates and makes it that when you reach the effect of -1/+1 you will be well prepared.
