Official rulings

The 8 most recent official rulings for Valki, God of Lies // Tibalt, Cosmic Impostor, newest first.

• 2021-02-05 In the Commander variant, a double-faced card's color identity is determined by the mana costs and mana symbols in the rules text of both faces combined. If either face has a color indicator or basic land type, those are also considered.
• 2021-02-05 If an effect allows you to play a specific modal double-faced card, you may cast it as a spell or play it as a land, as determined by which face you choose to play. If an effect allows you to cast (rather than "play") a specific modal double-faced card, you can't play it as a land.
• 2021-02-05 To determine whether it is legal to play a modal double-faced card, consider only the characteristics of the face you're playing and ignore the other face's characteristics.
• 2021-02-05 While resolving Tibalt's last ability, you'll add {R}{R}{R} even if you don't exile any cards.
• 2021-02-05 The emblem given to you by Tibalt allows you to play cards exiled with that specific Tibalt, Cosmic Impostor, even after that Tibalt leaves the battlefield. If a different Tibalt, Cosmic Impostor comes under your control, it's a new object (even if it's represented by the same card). Of course, the new Tibalt will also give you an emblem so you can play the cards he exiles.
• 2021-02-05 The cards exiled by Tibalt's loyalty abilities are all exiled face up.
• 2021-02-05 There is a single triangle icon in the top left corner of the front face. There is a double triangle icon in the top left corner of the back face.
• 2021-02-05 You don't choose which creature card exiled with Valki that Valki will become a copy of until that ability is resolving. (In many cases, the value you chose for X will give away your intentions.)
