GGblue

Pause for a moment to consider what Granblue, if given the bare minimum, will be capable of with G era support.

First;
On-stride CB1 revive one Grade 3

Regardless of where the GB2 ends up going, this is strong. Real strong. Lack of being repeatable is what made Pinot Noir unimpressive to most, and that's alleviated here.

Second;
Stride enabling/On-stride fetching Grade 1

You secure the ideal ride whilst simultaneously loading the drop zone for it next turn. That ability to discard any card is quite absurd.

Third;
On-hit revive one G Unit

Stronger than Royal Paladin's Gablade by far.

Fourth;
GB1 on-boost revive one Grade 2

The thought is so scary that I feel it'll end up having a retire 1 cost tacked on.

Beyond these, expect bonkers things like GB1 Chappie stand trigger and an unflip engine of the gods. The persona flip G Unit, though... that I can't imagine. At all.
