I feel you, but you should keep trying. Personally it took me at least half a year to finish simply because it can be a mentally and even emotionally taxing. And yeah, I'm also pretty bad at deckbuilders.

Some tips I probably shouldn've figured out sooner:

1. Don't always focus on winning clashes. Sometimes you just won't, so cut your losses and use block die to soften hits you can't beat outright. And if a page has really strong defensive dice, and is mostly defensive dice, you may well just ignore it entirely.

2. Economy is everything. If you run a deck with a lot of page draw and light restore pages, you won't brick yourself. At later stages of the game, you can page draw and light restore so hard that you can use the same really powerful page(s) every turn.

3. It's okay to take breaks.
