Too late. I shamed my family, my community, and myself with a paltry 0-3 showing. I've been playing this game for a year and still suck...
for what it's worth, if you want to get better at arena, there are a lot of resources on how to do so.
in my experience, if you go through the whole draft just picking the best card you're offered (with maybe some
slight attention to curve in the last 10), then play every single turn to maximize your stats on board and minimize your opponent's, you can go 6-7 wins pretty easily. if you start playing around your enemies' possible cards whatsoever ("7 mana coming up against a mage, i'll take the trade that's stronger against flamestrike") it only goes up from there
i think most people's difficulty is that they overthink it—worry too much about synergy during the draft phase, hesitate on playing cards that seem like they could get more value later on (e.g. choosing to play nothing instead of a blood knight onto an empty board because "what if it hits a divine shield later"), etc. i think basically ignoring card text and just focusing on stats on board would help more players than it would hinder, tbh
i know it can be disheartening but it's gratifying to get good at, and it just takes practice!
