Great run! I was also looking at Copper's video with the tempo mage deck, but it was way too expensive. Even your list, at the moment, but I guess everyone has to fine-tune deck lists to their situation. I also decided to ditch yeetmaster's list, as the deck-list is, indeed, very hard to pilot.. (what a noob that guy)
It's interesting that we both started (somewhat) at structure mage, but you ended up with tempo mage and I ended up with rush deception.. They are very different, yet I feel like they are also quite similar. Playing early cards for the board advantage, generating value with cheap legendaries, etc. I also got 19 wins this weekend, what a coincidence :D

Btw, as I have seen you around a lot here with a bunch of numbers, do you track your wr runs? I'd love to know what your average/best runs are.
