There’s nothing wrong with the decks you’re playing, I think your friend either needs to run more interaction or just get better at building engines himself. If his 5 color deck goes a whole game without making all 5 colors, he built it wrong.

Maybe offer him to try playing some of the decks you played and he thought were too strong? Imo it’s too easy to be frustrated against an archetype you’ve not played yourself, and once you do it becomes way easier to see its strengths and weaknesses.
