How to create decks and import decks

I can make some if you need them.

The process is a little laggy at the moment but how it works is:
Go to your collection.
Make a new deck.
Hit the weird hashtag like symbol on the top of the new deck to start editing it. (Numbers will appear at the bottom of cards if things are working right. Sometimes you have to hit the button a couple times, but make sure to wait a few seconds in between clicks incase it is just lag.)
Left click to add cards, right click to subtract cards.
Save deck.
Click the little control symbol to set it as active.

Unfortunately as of today matchmaking may be down temporarily.
