Can the HJ MAKE you play with English cards?

[Skitty]

If you were at a tornament in the US and have Japanese or some other language cards in your deck, could the HJ make you use English cards in your deck? (Assuming that you have an English version or card dex outside the deck) I know that the HJ makes the final call, but can he/she change the basic game rules in the prosses?

Quoting the answer from POP on this issue:

Depending on how much time it eats into the match to have to constantly reference your translations, yes, it could.

POP prefers that players use local language cards whenever possible. Foreign cards may look cooler, or be easier to get your hands on, but they can be a real pain for judges and players alike.

Why would you want to make things any harder for the event staff or for your fellow players?
