How do you all resist the urge to build a new deck every week?

I’ve been playing EDH for about 2 weeks, and every time I see a cool card, I immediately start brewing a whole new deck around it.

The problem is… my wallet is crying, my desk is covered in unsleeved cards, and I have three “half-finished” decks staring at me right now.

Do you have any strategies to keep your deck-building impulses under control? Or do you just embrace the chaos and keep brewing?
