Arikie, just a few things;
Ike
Don't firebird so unnecessarily to the edge all the time, if at any stage he grabbed the ledge, you would've died.
Seriously, this Match up is so easy because of the characters. Stop approaching him, and just camp, he has a difficult time because of his size and speed.
Don't play with an Ike when he's low off stage. You don't want an Aether in your face. Instead, stay on the ledge, and wait for him to Aether. Roll away when he does this. Keep trying to bait it, and after his limit of 3 he'll be forced to get up, so keep an eye out. He's very easy to keep on a ledge or punish him for getting up.
What happened at about 45 seconds in the first game? You screwed up your chain grab, lol!
Whenever you recovered, you had a habit of always recovering with phantasm up high.
At about 1:34, if you're going to recover and land on the stage like that, it's always good to cover yourself with a laser as you land.
Game 2
For serious. Stop screwing up the cg. XD
Walking cg. Running cg is unsafe. (Tripping)
Most of your SHDL's were shot high. You need to shoot one high and one lower for it be effective most of the time. The exception being when they're in the air or standing on a platform.
Snake
If you have Snake on the edge with a grab, it can sometimes be better to just release him there by pummeling. It puts him in a TERRIBLE position. If he's low enough to be dthrow > dair do that instead though.
How did you lose? Rofl.
Marth
Stop approaching dude. =/ If the Marth had any idea of Falco he would've loved you so much.
