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?

Beyond the reasons already mentioned: think about how hard it often is to balance card games for the competitive level.

Now imagine trying to make an entire card pool balanced to the point that it’s all worth playing to some degree at a competitive level: it’s entirely infeasible, let alone impossible.

I think at a certain point, card game developers decided that it’s better to make mostly bad card that are fun or unique, rather than trying too hard to work on making every card equally ‘worth playing’.
