Speaking specifically about his tourney deathspin variation, his b14 is his main combo starter (aside from 11 or 21 at close range) which should be hit confirmed into tele or b143 on block to keep him safe. Other than that he has his f32 which should rarely be committed to, the lingering threat of overhead to low and the fact that his f3 is only -2 on block leaves options open, f3 into grab, f3 into f4, f3 into b14. His death spin special is an 11 frame mid that can punish other characters advance on reaction and covers both the air and the ground. It's actually quite difficult for other characters to get in, and if they try and zone, it seems like most characters projectiles can be punished on reaction with his teleport this time around. Time will tell, but I think it's abit premature to call him trash on release day.
