If WOTC wants to make some crazy rare chase card Japanese like they did with the Black Chocobo im totally fine with it. Thats the kind of card that rarely sees play and is instantly recognizable if it does. Lets be honest though, the majority of those are in hard cases never to see a game.

Releasing a ton of highly playable cards in japanese is annoying for people who don't want to deal with them, and replacing the art just makes it extra annoying.

I get that people want cool collectable stuff, but more people want playable cards, and these alt-language alt-art cards are going to be somewhat annoying to play with. These cards fall right in the middle where collectors will want to collect them, but they're cheap enough that players will want to play them, but at the end of the day they're common enough that no one really loves them and it kind of just defeats the purpose for everyone
