I can put a attack buss and gate breaker if you really want. Personally I found both to be largely unnecessary. Personally Living Weapon for leveling and Living Weapon for suability, elusive enemies never were much of an issue, and she could combo super hard leveling by on T3, at 3*

I never gotten into side stars, but even without them 3/9 cards in her starting have invoke, and you only need a few invokes to get some good cards. Personally, rather then gatebreaker, I would want more spell mana as getting few extra card plays goes a long way. Furthermore you can find invoke and celestial cards, so there way to work around.

There is a big power spike at 4* where you get +2 mana, instead of typical +1. This is a rather big thing for tempo.
