What was your “finally sitting with the grown ups” moment?

After being stomped for 3 weekends straight, something finally clicked in my head about my deck. It had to have multiple winconditions, I had to learn when not to overextend and how to punish those who did.

So I just did more cuts, fixed my mana curve a bit more and overall just piloted it better. I went 3-1 today, was no longer perceived as the new guy because I turned the game around in 2 of these victories. I finally did some stomping of my own.

So, what changed and what deck/tech did you use that led you to “oh, shit, the playfield is even now”? Like that moment that boosted your confidence that you can hang with more experienced players and they could and should target you mercilessly because you now had the answer?
