Thanks for all the responses guys. Super interesting to hear other peoples opinions on it, especially those of you who speak multiple languages.
This coming from your classic ignorant Brit who can only speak English (not through lack of trying, I'm just naturally very bad at learning other languages it turns out).
I'm in the same boat as most of you it seems. I have no problem with it at all, but would definitely prefer it if the person using them to have a good grasp of the card if they're going to include a version that is in a language they don't speak just to avoid any confusion. That said, as Akira Foxmind pointed out, sometimes I have to check my English cards too so someone checking the wording still wouldn't overly bother me.
I was mostly asking because I've started picking up singles in other languages just for something different. So far it's just been cards I'm incredibly familiar with like
Xathrid Necromancer, picked up a bunch of Italian Command Towers etc. However, I found that you can get some real good deals here in the UK on singles in other languages. For example, I managed to pick up a Chinese
Necropotence for a fiver. It's usually £20+ here so I snapped it up at that price. My play group is super
chill with everything, including cards in other languages, but I was just curious as to whether or not it was something other people had strong opinions on either way.
Thanks again for all your responses.
