Diddy Kong's Counter Picks

Don't use banana when you're at a high %. Getting knocked high or offstage can leave the banana free for your opponent to grab. If they use it properly they can confirm a kill

A skilled player will know you want to throw the banana at them when they land. Mix this tactic up by throwing it at them in the air when it can give you the upper hand.

When you're holding a banana, the opponent knows you'll try to throw it at them. Which will most likely incline them to shield, so to punish this, go for a monkey flip to their shield. A Nice Mixup

If you are WAY above your opponent you can side b and then you can reverse your whole horizontal momentum with b reverse down b or b. For kills: at about 140 d tilt to u smash and at ledge d tilt fair

Ok first off, you want to set up a tech situation on a platform. Then you pull a banana peel, catch it and throw it at the opponent. You then platform drop and rinse and repeat. Infinite for days.
