To add to this, when you're deck building, you want to think about what you'll be doing. You want your deck to give you the cards to fuel your winning image, and that's what you'll do every game to win.

The only exception is a toolbox deck that focuses on techy abilities that you would combine to eventually whittle away at your opponent. But that usually relies on some sort of tutor engine like in Dungeon World Adventurers.

In other words, looks at the Legend world players in the anime: they all focus on an attribute, and a certain play style. That's what you want to focus on. It's fun to do things however you want, but in the end, if you want to be strong, your deck needs synergy, focus, and efficacy.
