to win do you smash attack to victory? are aerials your game? do you chaingrab? or a very powerful b move like falcon paunch? you can say anything for it.
mine is to weaken my foe with small and quick attacks to build up damage (arrows blasters a combos tilts) . when the time is right...go in for the smash. its also good to use aerials.
Many different strategies for many different people.
For me, it depends on the circumstance (items [I don't encourage them], Smash Balls, etc.). But mainly, I would to dodge alot of attacks and use every attack I have for an advantage.
My strategy is punishing mistakes. I put pressure on my opponent with aerials spaced just out of range. Sometimes I hit them "accidentally" with said aerials. I wait for my opponent to make a mistake under pressure, and then punish them for it by going into all out attack mode. I LOVE spiking and gimping recoveries. :3
i cant really say beacuse i main as pkmn trainer so i have diffrent strategys for diffrent pkmn like for example squartle i love his areals so i always sH then do a N-air
easy battle in the moment
dodge when i get the sense of danger
and keep my speed really high (i do this with bowser muahahhhahhaaa)
use the speed for running attacks to get damage up as well as my enemy and then slam em with a normal A attack follow them in mid-air and use the side arial attack then use a powerful arial move to knock em out
of course this changes depending on the character
thats my basic bowser strategy
my lucario, sonic, and snake ones are way different
