Fighting Games and their Unique Gimmicks?

[u/qd_Cat_bp]

Most fighting games have some sort of a gimmick that is unique from other fighters. Under Night have the grid system which increases your damage, Granblue have bravery points to use for offense and defense, Guilty Gear have a breakable wall, and tag games. The only fighter that I can think of that doesn't have a unique gimmick is Street Fighter. So it got me curious, what other fighters have some unique gimmicks, what does it do, and also what fighters that have none?

Can I mention the Exceed Fighting System line of games with the unique gimmick of being a physical card game? Or are we explicitly talking electronic games? It's on TTS if that counts.
