An Idea for a Tactical Mode for Smash

I have some crazy ideas for a togglable system for Smash Bros. A Simpleton mode which is plain 'ol Smash, or Master Mode where the over the top wavedashing, L-Canceling eSports action happens but also incorporates Fire Emblem's Weapon Triangle and Pokémon's Elemental Types, and since there are about 58 Characters in the latest installment alone, there's a lot to work with, so I'll start with the Obvious, Corrin is a Water-Dragon Type, meaning he can easily beat back Bowser's Flame Breath, but when Jigglypuff shows up with a Fairy-Type Moveset and his Nohrian siblings may as well be waiting for him to show up in a Full Body Cast. Likewise Pit can soar through the Air, But that leaves him open to an Arrow to the knee which could launch Pit's winged face back to Skyworld, but a well aimed Shuriken can pierce as sharp as a spear. Any other ideas you wish to contribute with the rest of the class?
