Valki, God of Lies // Tibalt, Cosmic Impostor is two cards in one: a two-mana disruptive creature that strips opponents' hands on entry, and a seven-mana planeswalker that exiles everything it touches — the cost is that you rarely get both effects in the same game. Tibalt's static ability turns exile-matters engines like Prosper, Tome-Bound into pure value, and the Crackdown Construct interaction (activating Tibalt's minus ability zero times on a passed-priority loop) was notorious enough to accelerate bans in older formats.
Best Commanders
Commanders with the highest synergy
Prosper, Tome-Bound
Prosper, Tome-Bound triggers off cards played from exile, and Tibalt's plus ability exiles the top card of each opponent's library and lets you cast those spells — every activation feeds Prosper's treasure engine directly. Valki, God of Lies // Tibalt, Cosmic Impostor is in a third of all Prosper decks for exactly this reason.
Nicol Bolas, the Ravager
Nicol Bolas, the Ravager demands the Grixis pie and rewards haymakers that disrupt opponents' resources, which is exactly what Valki, God of Lies // Tibalt, Cosmic Impostor does on both sides — two-mana hand disruption early, a planeswalker that exiles permanents late.
Don Andres, the Renegade
Don Andres, the Renegade cares about playing cards from exile and generating value off stolen or exiled resources, making Tibalt's exile-and-cast ability a direct synergy — Valki, God of Lies // Tibalt, Cosmic Impostor slots in as both a threat and a repeatable fuel source.
Nathan Drake, Treasure Hunter
Nathan Drake, Treasure Hunter rewards casting spells from unconventional zones and values the treasure subtheme that Tibalt's activated abilities enable, so Valki, God of Lies // Tibalt, Cosmic Impostor pulls double duty as an engine piece rather than just a threat.
Esika, God of the Tree
Esika, God of the Tree's The Prismatic Bridge back face lets five-color decks cast any legendary or planeswalker for free off the top, and Tibalt is exactly the kind of expensive planeswalker you want to cheat into play — Valki, God of Lies // Tibalt, Cosmic Impostor showing up in over 23,000 Esika decks reflects that overlap directly.

In Commander, Valki, God of Lies // Tibalt, Cosmic Impostor earns its slot in any black-red deck that can exploit exile-matters payoffs, with Tibalt acting as a late-game engine that generates card advantage and removes threats simultaneously. In Legacy and Vintage, the card briefly dominated after players discovered that cascade spells could name the cheap Valki half but put Tibalt onto the battlefield — that loophole was closed via rules changes and bans, but the card remains legal and sees fringe play in fair shell lists. Modern and Pioneer both allow it, though the cascade exploit is neutered there too; it shows up occasionally in Rakdos midrange as a top-end threat that doubles as a two-drop in desperate openers. Oathbreaker is where Tibalt itself can serve as the planeswalker half of the pairing, giving Valki, God of Lies // Tibalt, Cosmic Impostor a unique structural role no other card occupies.

Current price
$4.08 cheap tier
At $4.08, Valki, God of Lies // Tibalt, Cosmic Impostor sits at the cheap end of mythic double-faced cards despite being a genuine multi-format card — that price reflects post-ban deflation from the cascade era rather than any drop in raw power. It's a strong pickup at this price for any Rakdos or exile-matters Commander build.
