my favorite one is not really a combo but more of a mindgame, I jab cancel into a throw, any way to mindgame into a throw is good with link cause it makes opponent block less and dodge more which is nasty cause all of links kill mechs are dodge counters when placed correctly. best combo in the game for link is a 140% bomb-dac or z-air-bomb-dac or just Z-air-dac. i try to not upsmash much as a damage doing move because of diminishing returns, his dac is easier to hit and less punishable then his D-air cause of its suprise element. DAC has 2 variants though there is an extended DAC and a short one, the short one is done normally, the extended one is done like a shoryuken in streetfighter rotated 180 degrees cause you have to hold diagonally up/forward after a normal DAC and link will fly across the level at a longer distance. once the 2 versions of links DAC are mastered it become more of a consistent comboing tool. The hardest combos to do in the game for link are a bomb-slide uptoss into throw- up its a throw that kills at high percent and i've only landed it once cause its rather impossible. the other one which only legan has perfomed once is boomerang, jab-lock to the edge then meteor smash downtilt. 0%-death combo like falcos.
