Rood (A.B.A) vs GastlyGrave (Slayer) - Guilty Gear Strive

Celestial Challenge Loss #1
Hate this disgustingly bad designed challenge, my bad i should've played better.
More importantly I should follow my rules and stop greeding, I'm not a good player therefore i must understand my limitations which are many.
Not to mention the whole night was either bad matchup for ABA or Slayer so yeah lol.
if i mess up once vs Slayer I lose even if I have a lead the same can happen to him obviously.
IMO ABA is probably the best character rn vs Slayer but I'm not playing properly.
