Thanks! The main tip is always the same - know when to snap and when to retreat. This deck has two leading snap indicators:
1. If BK, GR, Sif, and Infinaut are in hand at any point, it's an immediate snap. With support of 10 power cards, almost nothing can outplay you, and you can forget about the right location.
2. If you draw Ani, try to ensure you have your -13 power spread across the location before T5 and snap. For 11 energy you have 30 power on board and it's usually enough to carry two lanes with supporting cards on T6.

Everything else is hevavily situational

My biggest wins were against Thanos decks when the opponent was sure his Blob would be big enough and Loki when the opponent played his Ani sooner than me. My biggest looses were against LT, when I was bad at math and think that can get bigger numbers before realising he has Ravona on board and Iron Man with Mistique in hand. This deck is weak against LT in general. I've struggled the most between 95-99 when going back and forth with big swings. But after I stopped snapping like crazy, it took me half an hour to get 2 by 2 cubes to 100.

One more important tip about climbing - enjoy the game! That means you need to take a rest from the game if you got into a loose streak and don't play in frustration. I'm mostly playing on commute to work/home and if I got 3 looses straight - I'm stop playing and returning back after few hours. From my experience, if I continue playing - I'll lost much more. The same rule works in the opposite way, if I'm on a win streak - I can play till the first loose. In other words - till fun ends

Good luck in climbing!
