Card Collection Feature

{"ops":[{"insert":"Hi there! Card Collection is already a feature, accessible from clicking on your username in the upper right-hand corner of the page. If you have Collection Flags turned on in your Account Settings, cards in your deck will get a green stripe in the upper left-hand corner if you have an exact copy of that card in your collection or a blue stripe if you own a different version of that card. Additionally, from our card search menu, you can toggle on \"Collection\" so that it only shows you cards in your Collection while you're building a deck. \n\nHope this helps!\n"}]}
