I can't really see Daisy as her own character, i think she would fit as a Peach clone, but if she was to be her own original character, heres what i think she would play like.
Moveset
-Striker Kick: Daisy kicks upwards in a very fast motion, Doing atleast 15% damage.
-Ball Smash: Daisy charges her Bat and Thrusts it forward, dealing atleast 30% damage, but charged up does 45%
-Upward Slash: Daisy does a simple Punch upwards, dealing atleast 10% damage.
-Downward Kick: Daisy kicks at her opponents feet, dealing atleast 5% damage.
Grabs
-Strong Arm: Daisy punches the opponet, dealing 18% Damage
-Stomp: Daisy throws the enemy on the floor and stomps on them, dealing 15% damage.
-Backward Smash: Daisy simply pushes the enemy on the floor, dealing 5% damage.
-Upward Headbutt: Daisy Throws the enemy in the air and headbutts the enemy, dealing 10% damage.
Final Smash
-Daisy doubles all of her attacks by 50%, and getting hit makes you get set on fire for 3 seconds, dealing an additional 5%
