You can take your time and effort, but it must follow the format posed with Ravnica when you make a guild. The ones who make guilds I like... I will place a favorite on ALL the cards you make when it's done.
When I see you've made those 60 card decks, I will also judge them in a few divisions, rating such from 1-10:
Lands - Creatures - Enchantments - Artifacts - Legends
They must be properly formatted decks...
