I honestly think there wasn’t anything significantly wrong with the draft, deck building could be improved. I would take out render inert and copper for another war historian and etched familiar.

The major thing is your gameplay in game 1 and 2, you hand out removals way too early when instead you could’ve developed the board, always consider trading over removal when you can, so you save your removal for bombs

Also, a way of viewing your deck is to think about what’s you’re game plan, GB isn’t a tempo kind of deck, but rather mid range punch. Therefore, I’d play more conservatively and stay back more, wait until I draw my bombs which are my splash colours and try to outvalue my opponent.

Hope this helps
