it's not a combo vid. its just a vid of Ike ownin' everybody in sight.
and sadly SKing, irape4free is right, most of that stuff is incredibly easy to do. the ledge guard and spiking in the vid was easily the hardest thing to do cause Ike has a horrible off stage game. but the rest of the stuff was really easy. i used to main Ike(before moving on to Kirby & Olimar) and i could do almost all that stuff.
it's a neat vid but it's not showing some of the better Ike strategies and combos out there.
