RE: Toad
It was mentioned a few pages ago that most of the franchises on the roster feel "complete" in terms of characters but I'd have to disagree when it comes to Toad. He's been a part of the series basically since day one, and his role has only grown since then. You really can't have a Mario game without Toad, and when you – rarely – do, it feels really strange. Not to mention he's always front and center in the playable rosters of the spinoffs (except recent Mario Party, for some reason).
Toad's strong presence in the Mario movie gives me some hope, alongside Toadette's rising prominence in the series. In some ways, she's even more prevalent and relevant than Toad himself. Of course a prerequisite for getting Toadette is getting Toad himself, so I feel like their combined chances are a bit higher than before.
It all comes down to Sakurai changing his mind about Toad as a character and his position in the Smash universe. Him being Peach's meatshield was funny the first time I guess, but since then? It's been an injustice to both their characters.
In any case, whether he becomes playable or not, I hope the Toad move is retired. Peach deserves something better and Daisy doesn't even have an association with Toads. The move also falls into the "summon X character to do something for you" category which I don't like.
As for what the replacement could be? There's plenty of options for both princesses. Stella from Princess Peach: Showtime! could basically fill the same role as current Toad, except she'd transform into a ribbon to attack. The other alternative (that I prefer) is the War Fan from Super Mario RPG. Her other two weapons from that game (parasol and frying pan) are already in Smash, so it'd be cool to complete the trifecta. Peach assumes an elegant defensive stance with the open fan covering the lower half of her face. If she's hit, she rapidly fans forward unleashing a wave of hearts. I might just be a fan (pun unintended) of this idea because I main Kitana in MK, lol.
For Daisy, I could see the Bubble Flower being used. This one wouldn't be a counter at all, but rather a slow projectile that traps opponents in it and allows Daisy to jump off if. Randomly blowing a spit bubble would be strange and kinda gross for Daisy though, so I think she should hold out the Bubble Flower like a bubble wand, and blow it gently. More dynamic animation. The other option would be to just have Peach's War Fan, but customized for Daisy. I wouldn't be opposed to a custom floral fan, since she already uses her own parasol and Peach's frying pan. Would be cool for consistency.
