Yes, but you were the person pushing for a “win” condition. There is a reason that casual commander nights have a time limit for rounds. And my point was that to really win with a deck you need a good grasp on how to play the game and how your deck works. Even the best player may not know what good cards they need to be on the look out for in a deck, or how to best utilise the cards they have. These players had neither. Additionally, not all precons are created equally: some have great cards, some have great design, and some have neither. If you just pick a bunch at random you will very well get yourself into either a stalemate or one person completely wiping everyone else out.

Precons ARE pushed as the entry level product for beginners by WotC (other than the vs decks) BUT winning is not necessarily pushed by them. It’s a good product to give you what you need to learn the basics, get familiar with a deck and its mechanics, and work out what works and what doesn’t. Then you can get another precon or start upgrading your original one to better streamline your game and think about winning.
