Teleporting Detonator that scales well in long fights.

S

+1 CD teleport

+Strong scaling throughout fight (especially in wave battle scenarios)

+Highest base ATK in Fire

-Teleport is extremely limited in terms of range.

Gram combines solid damage with an excellent utility effect in low CD teleportation. He also has relatively few weaknesses - his kit just kind of mostly works, except for some small start-up. He's the epitome of "utility + stats = good unit".

Note that his overall damage is comparable to (pre-refinement) Charon, but slightly less consistent. It's not enough to make or break his output, but it's worth mentioning.
