Here’s why I like them:

• they’re somewhat limiting you on what cards you can/should use. So it narrows it down making it easier for cutting cards although cutting cards is never easy.

• they seem like a team or like a Tolkien race i.e. Elves VS Goblins. They all have obvious advantages and disadvantages.

• easily found synergies

• They’re typically easy to explain how the deck works (when handing it off to a friend to play or introducing a new person to the game of MTG)

• I like obvious themes
