Notes as I'm watching: You squall too much at him, and eat utilts. Don't drop your grabs (obviously). Think of his utilt like MK's shuttle loop, it's a get out of jail free card. You fell for his uair and bair shenanigans a whole lot. Don't be aggressive against snake in the air until he's out of options, like he already burned his upb and is too low for breverse to save him. That's game 1, I have to run, will edit comments on the others later.
Game 2: You started off PERFECTLY, shame you dropped the grab...twice. Ugh, don't go for those upbs, they don't work. Stop squalling you get punished EVERY time. Rather than stepping on a mine to blow it up, bounce ice blocks off it and chase them, it's a great setup that gets me grabs all the time. Silly SD second stock x_x. When you had the grab at the edge, either do my 0-death, or spike and immediately dtilt, it ***** snake. When Snake is forced to tech, don't be afraid to bair him out of it.
Game 3: First off, CS? Weird pick, but okay. Ugh, more upb. When you get a grab and nana isn't there, just uthrow, at least you get something out of it.
General notes: You grab too much. Like, obnoxiously, scarily, omfg, too much. You should NEVER be dash grabbing snake, if you're grabbing him, it better be out of a shield or a pivot, Snake eats dash grabs. I suggest going NOT FD against Snake, I greatly prefer BF and Lylat for neutrals, FD is too big. You played too aggressively against him, as well. If he wants to camp, let him, you ran after him almost immediately. Squall got you punished a lot, and you made a lot of silly mistakes, which against Snake is ewwww.
And yea, it was me about hitlag d/s, it's pro against Snake and Diddy.
