A feature that would be nice, especially in public decks is a filter to eliminate a pattern, like for instance decks with all 5 colors, since incredibly many make a "deck" with one of each card in a set. These decks are completely useless when looking for deck ideas; e.g. "I want a deck with card X and card Y" might return 50-100 separate, but identical, set-decks and 5-6 useful hits.

Maybe we could get a variant tag for collections which would exclude them from deck searches?

A "collection" tag and the ability to exclude one or more variants from a search would certainly solve the issue.

Seems reasonable. Hey Sebi!

of course, if only registered users have the ability to use this tag for their collections, it will be pretty much useless.

unless it is automatic, by looking for decks with 1 of each for a full set or more; which I guess is a lot more work to code in.

even better might be a new type, like "idea" and "built" decks, with a freely accessible filter for collections.
