Makes me wonder what I'm doing wrong with my decks
I kinda feel the same... I'm trying to improve my ingame turn-to-turn decision making. Watching Mythic matches on YT helps me a lot even if no-commentaries. But for newcomers like me the best way is just practice and practice a lot at the highest rank possible.
RE: I have to share a whole set of budget decks that perform extremely well at Mythic Rank on Weekend Event! (deck codes included)
