When viewing the collection, have a toggle-able format option. Filtering by sets is nice and all, but is really not helpful if you don't even know what sets are legal in the format you are going for.

Seems simple enough to create a filter for format, though obviously on the back end that requires updating whenever the sets rotate out, but you have to do all that anyway already, so why not make format filters? Sometimes i just want to look at only cards valid for commander("brawl") and it's a pain to look through everything and then find out the card is not even standard.

Additionally, it would be nice if we could have 2v2 or 1v1v1v1 formats again, and also a ranked commander/brawl please. I hate all the current modes that are ranked and ranked is the only way to get rewards, seasonally, so please give me a reason to keep playing
