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

This is also true for any effects that were affecting the God when it was originally a creature
while this is a common, is a lot when it's usually an uncommon 3-drop that fills this role

(2020-11-10) If you play a card from your graveyard and then have a new Muldrotha come under your control in the same turn, you may play another land or spell of that type from your graveyard that turn
Also, on the early turns this is a three-drop but later on in the mid or late game you get three of these for just a six-mana investment
