Just be forthcoming about what youre selling, and dont try to trick people by acting like its anything other than a big box of commons
To that end, we also dont have a huge amount of room in 60 cards, so Id suggest only looking at the cream of the cropcards that have a good upside outside of being merely a good body
I think the best thing about the format is that no matter what happens we have access to the vast majority of the cards (or all of them if your group is into it) and that since our decks are eternal we can just build as we go
Great for Aristocrats decks that need more sacrifice fodder, or, obviously, Treasure decks
Sevinne offers an interesting build around as he supports not only flashback, but also aftermath, retrace, and jump-start to really carve out a graveyard spells-matter archetype, leagues clearer than before
When I say budget-friendly, that doesn't always mean cheap decks comprised of commons and uncommons
