Spellbreaker isn't an archetype. It's a speciality or sub-archetype at best, the ability to counter/negate magic.

Having physical capabilities in addition to magical abilities is nothing new. Her physical capabilities also aren't all that bad, considering she's barely a ten-tonner. Compared to chars like Bayonetta she's both slow and weak.

The only part where you have a point is your statement on the snowballing, and I might agree that that's overpowered. But the rest of what you were saying was nonsense.
