Ruling Local Language Question

[matheus_been]

Hello everyone, I'm new on pokemon tcg, and I've a little problem with my deck, I need a few supporters cards and 2 Zoroark, but in my country its hard to find these cards, but i found then on ebay, and they're in english, and my cards are in portuguese! Can I mix those cards for championships? or the deck need to be in one language? or can I use only english cards in competitive?

Rule of thumb is English cards can be used anywhere. Beyond that, here is a list of what is considered 'local language':

Canada
Local—English and French

Europe
Local—English, French, German, Italian, Spanish, and Portuguese

Mexico
Local—English and Spanish

South America
Local—English, Spanish, and Portuguese

United States, Asia Pacific, and South Africa
Local—English

Assuming you live in either Europe or South America, you are free to use both Portuguese and English cards in your deck, since they're still considered local (even if you don't live in Portugal or Brazil).
