Guys... the perfect nerf has already been given on page 20 by a very intelligent user named DarkBaron12390 who has garnered much support over his idea.
I lol'd. Accretion count increase and instant BH cast? What?
Yeah, the problem is the user gets both PC and quanta control with a black hole. There is no downside. My idea is follows
•Starts at 0/1
•HP increase remains the same, +15.
•BH when HP > 45 (iirc the post had a typo with 50, so no PC increase)
•Black hole activates immediately on both players.
•If your mark is gravity, then it activates on only the opponent.
This decimates the rainbow abuse of SoF, mainly.
