Nice job! Do you mean like, on your winning run you spent more time staying in early rounds not winning so you can buy more cards or something?
Yes, you got it.
In the "first" runs (like 20 or more, I'm a stupidly stubborn person) I was trying to "win" the first rounds as soon as possible, theoretically to have more turns in the late stages.
I started winning the game, spending every turn that I had, and closing on the last turn, cleaning the deck and buying more powerful cards.
I think I had won one of the games having started with not more than 4 or 5 turns.
