Vs Link It's good to avoid any bombs/boomerangs I throw at you. Working on your movement and on your shielding will help a lot. Also, if you know how to approach well, with SHFFL nair maybe, you can probably kill me using Doc's superior speed and mobility. Work on reading my techs and hitting those f-smashes and down-smashes, it'll give you many KOs, even at low percent. I think Doc beats Link with simply with decent/good approaching and comboing. Using side-b for edgeguarding probably doesn't work very well but you can try it.
Vs Jigglypuff I think you need to use good spacing and aerials. I don't really know what to do, but I know that your dash attacks don't work because the hitbox is really low and won't hit me while I'm in the air.
I don't know why I wrote this here instead of telling you in real life, but whatever
