Collectible Card Game Headquarters

Why old decks not supported in Manalink with patches, I see cards not those in deck?
Why some new decks not work, when begin game you lose game?
What's card which appears at begin game in my field and opponent field?

Old decks are no longer supported because Manalink has a maximum limit of 2000 cards and we still can't break it, so we have to replace some cards with new ones and the choices are difficult.

Due to that fact, there are some decks that are obsolete on the new version and they need to be edited manually.

Someone posted a big pack of deck updated to the last update, you can search for it, backup the old deck and install the new ones

thank you very much for your answer, possible it is necessary to create faq for begginers.
