Just a card designed around lore and utilizing lore counters.

Enchantment, I wager.

Is the lore counter concept based on something else, or just something you wanted to do?

Whoops, I did forget the card type.

I may have lied about designing around using lore counters. The card was designed around oral tradition. Tales from the past seemed to fit the idea of lore, and creatures in the graveyard seemed like a good way to represent the past. I've been leaning towards giving green storytelling, but the graveyard made the card feel black. Anyway, having said and thought the word "lore" too many times, lore counters had run through my mind at some point and I took to them as a tool to make the design work.

All that being said, the card ended up here instead of temporary storage as this feels like a rare and set where I'd want this flavorfully isn't intended to have multicolor rares that aren't planeswalkers or legendary creatures.

Just get a dead Memnite, and you have unlimited Memnites. If it's a Dryad Arbor instead, then next turn you'll have lots of mana too!

Any 1 or less cmc creature in your graveyard goes infinite with this.

Yeah this should say "Non-token creature"

Still goes infinite with any 0 drop. What do you think of "Remove one or more lore counters from ~: Create a token that's a copy of target creature in your graveyard with CMC equal to the number of counters removed this way." There's precedent for that

Not as elegant as using X, but it does the same effect.
