Ive noticed that while some cards are sought after purely for their aesthetic appeal, which comes as no surprise given the beautiful artworks weve seen as of late, its often the combination of a cards playability and its desirability that pushes its value up
The card exiles all opposing graveyards when it enters the battlefield (leaving your own graveyard perfectly intact), and if that's not impactful enough, it also allows you to be able to cast any one of those exiled cards as long as it is in exile, for mana of any type
Then I heard about a little thing called tin fins from a highlander tournament hosted by LoadingReadyRun

Imagine playing it on turn 4
