extra filters

W U B R G

color identity, fits-within like deckbuilding: tick W and U and only white, blue, white-blue and colorless cards show. in the filter box: id:wu (or -id:rg to ban colors), or id:c for colorless only

$ to

price bounds, in the currency picked below. cards with no listed price are hidden by any price filter. in the filter box: usd<=5, eur>=1

the currency every price shows, filters and sorts in. it applies itself and the site remembers it. in the filter box usd and eur always mean themselves, a bare price<5 follows this switch

MV to

mana value bounds (converted mana cost). in the filter box: mv<=2, cmc>=4, both spellings work

the card's type line must contain this. the filter box takes any word, not just the list: t:legendary, t:aura, or -t:creature to exclude one

commanders only

only legendary creatures, the cards that can lead a commander deck

hide game changers

hides cards on the official game changer list, for lower-powered brackets

include illegal

cards that aren't legal in commander (banned and such) stay hidden unless this is on
