Could you elaborate on this "smarter deck builder"?
Our goal was to add a feature that made it easier for players to build competitive decks using the cards they already own. This will be a great help to people who don’t own all the cards for a specific deck they’d like to play. It’s also great if someone knows 5 or 10 cards that they want to put into a deck, but they aren’t sure what the rest of the deck should look like and want help with that.
The way it works is we gather information from all the decks that are being played and we see how successful each card is in these decks. We look closely at what cards you own, and what cards you have already placed into the deck, and find the best archetype that fits those 2 criteria. We then finish out the deck with the strongest cards that you own for that deck archetype.
Sometimes a deck doesn't fit into one of the many archetypes and in those cases we resort to a backup plan and give you the most powerful cards that you own in a good mana curve.
