In the case of your G zone, I would recommend picking up strides that are mostly generic to the clan, like Masquerade Master, Harri and the recent Darklord Princess, as well as a couple of g guards at least. Typically for Pale Moon, you would want to run about 11 strides and 5 G guards, though the numbers really don't matter since you just wanna try the format out for now. The second, and probably most important step, is to build your 16 card G-zone, a must have for pretty much all premium decks (even if you end up never using it). You can do that through YouTube or checking online for multiple lists. In that case, I'd firstly recommend studying up on the staples for your main deck, i.e., what all premium pale moon decks would use, like stride fodders (in your case, Masquerade Bunny). Well for starters, let's assume that you just want to turn that standard deck into a premium one without making many changes.

Since you're familiar enough with standard, this makes explaining things a lot easier.

Hello, and great to hear that you wanna try premium.
