Sagato is coming along real good. The thing is...I know DJ is my main and all but in all honesty, the matchup is pretty sided, DJ has great reach with the black foot (jumping HK) over Sagato's fireballs, so his fireball game needs to be either consistent with traps or trixies with fakes, keep in mind his arms are hitboxes after a fireball is released. Try to mix up the fireballs for different speeds, trap the enemy in any zone you can, low high, low high, set different speeds and what have you. Sagato is top tier, once you know the drill you'll be just like Nappy Nightmares, freaking beastie!
