Now, I could try to explain in my own words what that means or how they work within the rules, but that has proven dangerous in the last few weeks (did I mention that when you use a splice ability the card remains in your hand?), so instead I will refer you to the Champions of Kamigawa FAQ: Flip Cards The Champions of Kamigawa set contains ten "heroes" that are easily recognizable by their unique card frame: Akki Lavarunner -- Tok-Tok Volcano Born Budoka Gardener --Dokai, Weaver of Life Bushi Tenderfoot --Kenzo the Hardhearted Initiate of Blood --Goka the Unjust Jushi Apprentice --Tomoya the Revealer Kitsune Mystic --Autumn-Tail, Kitsune Sage Nezumi Graverobber --Nighteyes the Desecrator Nezumi Shortfang --Stabwhisker the Odious Orochi Eggwatcher --Shidako, Broodmistress Student of Elements --Tobita, Master of Winds You ignore the information on the bottom half of the card until the creature in play "flips" when certain heroic conditions are met

Coupled with the fact that The One Ring is a colourless artifact, The One Ring can be slotted into just about every deck, and it is seeing a lot of play in Commander, Legacy and Modern
