they have helped push Magic design forward, with tokens, full-art lands, split cards and dice-rolling all having roots in Unsets
And remember, just like with a normal Magic set, you get a basic land every single pack, which means if you could somehow pick up Unhinged or Unglued at MSRP, you'd quite literally be guaranteed to make money every single pack, despite the worthless rares, just from the basic land slot
It also happens to be a powerful payoff for both creature types
Commander players often dont pack much in the way of graveyard hate, so Im all about cards that can come down early to deal with reanimation targets and the like and then provide a big upside later in the game
If you are a mage that likes playing Krakens, Leviathans, Octopuses, and Serpents, I've got a deck for you
