Foreign language cards are entirely legal in official competition. I bought many of my dual colour lands on eBay from a German dude. Always passed deck inspection. Granted that’s literally over 20 years ago and I never placed higher than 17th in qualifiers, but I can’t imagine they changed that rule.
I’ve been to game stores that allowed proxy play as long as you had the original card. (For FnM)
They usually had the same rule for foreign language cards.
