Karn's Temporal Sundering card art
Karn's Temporal Sundering bounces a nonland permanent and takes an extra turn — that's a Time Walk stapled to a removal spell, and the legendary-spell rider means it's nearly free under Narset, Enlightened Master or imprinted on Panoptic Mirror. The six-mana cost is real, but any deck that can recur or cheat it out treats this as one of the format's most backbreaking extra-turn spells.

Commanders with the highest synergy

01
Narset, Enlightened Master

Narset, Enlightened Master

44.5% of decks · synergy 0.43

Narset, Enlightened Master attacks, exiles Karn's Temporal Sundering off the top, and casts it for free — the legendary-spell restriction is irrelevant when your commander is doing the casting, and chaining extra turns this way is how Narset decks end games.

02
Edric, Spymaster of Trest

Edric, Spymaster of Trest

36.8% of decks · synergy 0.36

Edric, Spymaster of Trest builds toward a critical mass of cheap evasive threats that fund extra draw and extra turns, and Karn's Temporal Sundering is the payoff that turns a comfortable lead into an unassailable one — bounce their best blocker, take another turn, repeat.

03

Peter Parker

30.9% of decks · synergy 0.30

Peter Parker rewards prowess-style spell chaining, and Karn's Temporal Sundering fits as a high-ceiling extra-turn spell that also clears a threat — the tempo swing of bouncing a permanent and untapping again lines up cleanly with what the deck wants to do in the late game.

04
Jodah, the Unifier

Jodah, the Unifier

10.7% of decks · synergy 0.10

Jodah, the Unifier cascades legendary spells into each other, and Karn's Temporal Sundering is a legendary sorcery that qualifies for every trigger — casting one legendary spell can chain directly into it, and the extra turn lets Jodah attack again immediately.

05
Jeleva, Nephalia's Scourge

Jeleva, Nephalia's Scourge

10.6% of decks · synergy 0.10

Jeleva, Nephalia's Scourge exiles spells from opponents' libraries and casts them for free, and Karn's Temporal Sundering is exactly the kind of high-mana spell she loves to steal and fire off without paying the six-mana cost.

Format Analysis

Where it lives, where it can’t

FormatVerdict
commander legal
legacy legal
modern legal
pioneer legal
standard not legal
vintage legal
pauper not legal
oathbreaker legal

Karn's Temporal Sundering is legal in Commander, Legacy, Modern, Pioneer, Vintage, and Oathbreaker — but its real home is Commander, where the legendary-spell rider is often irrelevant and the extra-turn effect at six mana is powerful enough to close games. In Legacy and Vintage, six mana is too slow when Time Walk costs two and faster options abound; it sees essentially no play there. Modern and Pioneer are similarly hostile — six-mana sorceries that don't win immediately on resolution struggle to compete in those formats, and extra-turn spells in general lack the redundancy to build around. Commander is where Karn's Temporal Sundering earns its slot: the bounce rider is a real bonus, decks like Narset can cast it for free, and the format's slower pace makes landing six mana realistic.
