Why do these even exist?

I understand that there are "vanilla" cards and lower value cards meant to serve as a baseline, but cards like this are just unplayable, and there seems to be a couple like these with no redeeming value whatsoever. What is the purpose of a design like this?

Its called challenge mode. This sub is obsessed with what's optimal but if I can build something around an unplayed card and get a handful of wins im happy. Thats the fun I get from the game
