Currency Converter Not Legal in Timeless?
When I try to build a deck with Currency Converter in Timeless, it does not show up at all when I search for it when I mark the legality as "Timeless." If I make the deck "Direct Game," I can find Currency Converter, but it is marked as not legal when I attempt to play with the deck. I have seen no announcements that this card is banned in Timeless.

Deck builder Sideboard cant count.
In deckbuilder, if sideboard has 8 or more cards the client will not save the deck and reports that “a deck can not gave more than 15 cards in the sideboard”. There were 8.
I tried with other cards and other sideboard sizes. 7 or less is fine. 8-15 is bugged to automatically think its more than 15.
I saved the deck with a small sideboard then reopened the deck and still encountered the bug.13 votes -

Brawl deck building bug, singleton caveat ignored. Deck is not playable
There is some issues with Persistent Petitioners. It is one of the cards that allows you to have "any number of this card on your deck"
But brawl is saying that my deck has an error of "too many copies of the same card"
Obviously, ignoring the card's caveat to the rule.
It's one of my best decks, I'd like to be able to play it.14 votes -
