Since the format was announced (back in early June), I have been working to come up with new deck ideas and strategies that can have a shot of glory that year
(I should also mention that this doesn't include reprints, so fetch lands are counted as Zendikar cards, not Modern Horizons 2 cards, so they aren't skewing the data.) While Modern Horizons sets add a lot of interesting new cards to the Modern format, at this point, it's clear that they also add a lot of expensive cards into the Modern format, which in turn ends up increasing the cost of playing the format
It does include free shipping after all
So why cant it see play here
The sweet spot for serious collectors
It's a standard for Sliver decks, but since it hasn't seen too many reprints, demand has bumped the price of Crystalline Sliver up a slice or two
