Mirran swords
The Mirran Swords are a group of cards featuring equipment artifacts that provide +2/+2, protection from two Colors, have a triggered ability that triggers when the sword's equipped creature deals combat damage to a player, and equip for 2 mana. The sword's triggered ability will offer two effects that come from the same two colors that the sword gives its equipped creature protection against. At first, the swords were released across sets that featured Mirrodin and New Phyrexia and only offered protection from enemy colors but now, more swords featuring allied colors are being released starting with Modern Horizons. Some swords have been reprinted in the Masters series, in Masterpiece Series, and even as judge Promotional cards. While many swords have received different art, Chris Rahn has created a piece of art for each sword so far.
