So I got some real match time with him last night and boy, you guys were not kidding about having a decent mid =/
played against my friends pretty decent supergirl and that matchup feels rough. like after a blocked ice (b12 ice breath) most people get to take a turn and press a button, but poor darkseid cant even reach her with his 2 . plus zoning her is not an option, she can teleport on reaction to punish. was able to bait a few times with d3 since it looks like lazers but nothing was gained other than having her in my face since the recovery is too long to punish the teleport punch whiffing (and she gets a combo still if she MB it).
when i could get it I found decent pressure with b1starter , d1 , 21 db1 , and instant stomp , but alot of his gameplan puts the opponent back full screen so its hard to keep the pressure up when you are behind.
of course, not every char is supergirl , or has her tools but it def opens up your eyes to what kind of issues he will have in this game.
