With that in mind, winning with a card like Joana
and then following up with an all-pilled Cliff
(assuming they play first) could result in an easy 2hk0 for you. Take the 2hk0 when possible, but don't overfocus on it. If you can win 3/4 or even 4/4 rounds, by all means do so. Your 26 or so point winning will make you happy. Basically, take this second strategy when you have a straight up better draw than your opponent, or your decks meta smashes theirs.
Basically, it all comes down to reading the situation and playing accordingly. I've come in the top 10 multiple times with t1 decks in t1 rooms (which is extremely good.) I don't like playing in the t2 rooms, though i sometimes venture there to try my luck at actually winning a dt. It's all about winning as many rounds as possible, losing with a point gain, and just playing as many matches as possible. Keep this in mind, and top 150 will be easy
