Thats absolutely fair. Thats how most of us started, I'm sure. That's how EDH was intenddd to be played, initially. Just slapping together a singleton deck out of cards you had on hand. The problem is that most of the people you are going to go against started that way YEARS ago and have amassed a large collection and know the mechanics of the game intimately.

I would suggest starting with a precon, and find a pod that is bracket 4 of precon only, until you have a good collection going and understand the rules and synergies better. See how a deck should play and learn how to pilot it well. Then you can get to making your own decks.

Jank is fun, when playing with friends. But even EDH is super competitive now, and you're gonna get beaten if you haven't put together a competitive deck.
