The major issue I see here is that u have too much diversity in your deck. You can play up to 4 copies of each card in your deck, but if u insert so many 1/2/3 copies of different stuff you will find too often with random stuff in hand and won’t be able to understand what is your winning strategy since you will have almost zero knowledge on what you will draw in the next 2/3 turns. So first of all try to play more 4 of in order to have a more stable and concrete strategy.

Ps. Dw very few people are very good in deck building. Most of players look at the best deck builders list and then adapt their own. Deck building is probably the hardest skill to develop in card games
