Yeah, the string itself its plus enough and also temporary hides smoke in the cloud allowing the smoke player to do a low combo starter, or a overhead starter.
The best part is that the string is special cancelable, so Smoke can cancel the could string into fully invincibility and apply a unseen overhead or low from there, he can also do cross ups, or crossup lows while at it.
My guess is, his basics BnBs will go around having his smoke bomb has a launcher, then his harpoon for the restand, and the cloud string to apply a mixup post restand, if they guess wrong (smoke has a fast overhead just as a fast low) he will be able to do it again.
So in terms of playstyle, he might be the up close with 50-50 mixup pressure, while sektor has a strong zoning into negating wakeups with his up missiles setups for continued pressure into his ex flame burner, and Cyrax is more of a (come at me bro) type of game with a lot of space control with his bombs, his neural will be insane.
Honestly i don't even want to think that cyrax is the strongest variation right now, of course its way too earlier to tell, but it felt like all 3 are pretty strong IMO.
