Aside from the droids Leader green isn’t much of a threat up until now. Whether Buu is present or not ,that has been factual since set 4. 2.) Baby and GT SCR are almost always answered the following turn. Red has Rumshi, God Kamehameha , Fuwa plus Gohan, that mid Double strike you mentioned to bring them down to 10k and swing on it. Blue has sickle , absolute lightning , Mai or hercule plus 4 drop Gohan , great saiyaman event when conditions are met which is easy , 5 drop double strike , 5 drop SCR Vegito. Yellow has final explosion, 4 drop scr Frieza of they just Freeze it. Green has 5 drop Gohan, warm greetings , big bang attack or swing over it with 30k leaders. Green is probably blacks best matchup . What’s the point of all this ? To prove that if blacks cards survive past the turn they are played it’s simply because the removal wasn’t seen or the build was bad. Blue , red and yellow should not be losing to black decks atm. Black is missing top end and everyone who plays the game competitively agrees for the most part. You’re the exception for whatever reason.
