Daisy vs Roy

Daisy has a good neutral against Roy with her turnips. Put on turnip pressure and force him to approach. If he tries to fair and catch them, run in and punish him for it before he can use them. Daisy also has a a decent dash dance game and a kill dash attack, so try to bait him out if turnips feel too risky. You can also fake a turnip pull by crouching, then dtilt into a combo of your choice or a tech chase. Roy doesn't have a projectile or reflector, so turnips are typically your friend here. He does have a counter, but its punishable, and you have a counter too.

Daisy can use a landing mixup with her float. She has a fairly good disadvantage against roy and many sword characters. Try to float above and bait out a move, then drift away and land. You can airdodge down if you have to, but try to save it so you can waveland into a more strategic position. Roy doesn't have any juggling moves that stay out for a long time, so you shouldn't have too much trouble.

Turnips are your friend here. Try to turnip gimp him, especially if he's far out. With his weaker horizontal recovery, a turnip or two can spell death. Dair is a good tool, and can challenge most of his options. Try using it above the ledge to cover a missed sweetspot or try to two-frame him. If you get him to use his jump and he's close, go for a fair. Often he'll try to fall instead of recovering high, which is easily punishable. He'll often not use his airdodge if too far out, as that forces him low before he can recover. If he does use it, go back to stage and turnip down. It may kill him if he hasn't recovered yet. Side special is also a great tool, especially for mixups. If you use fair and bait out his airdodge, then float back and bomber him for it. It'll send him out, which is a problem for him with his little horizontal recovery. That's about it for the basics. Try to push him out horizontal, make him use his jump with turnips or eat them, and hit him when he gets close.
