Klauth's Will is a modal board wipe and artifact/enchantment sweeper stapled together — and with a Dragon or Dinosaur in play, you can do both for five mana. Named after Klauth, Unrivaled Ancient for good reason, it's one of the most efficient catch-all answers available in Gruul.
Best Commanders
Commanders with the highest synergy

Klauth, Unrivaled Ancient
Klauth, Unrivaled Ancient floods the battlefield with power-stacked Dragons, making Klauth's Will trivially easy to unlock both modes — sweep the board of creatures and blow out enchantments and artifacts in the same spell.

Vrondiss, Rage of Ancients
Vrondiss, Rage of Ancients generates a wide board of Dragon Spirit tokens, which means Klauth's Will almost always qualifies for its full dual-mode effect while clearing the way for those tokens to connect.

Rosheen, Roaring Prophet
Rosheen, Roaring Prophet's Dragon and Dinosaur tribal focus keeps the creature count high enough that Klauth's Will reliably fires on both modes, doubling as a reset button and an answer to problematic permanents.


Ganax, Astral Hunter // Acolyte of Bahamut
Ganax, Astral Hunter // Acolyte of Bahamut builds around Dragons entering the battlefield, so the board state needed to activate both halves of Klauth's Will is built into the deck's normal game plan.

Miirym, Sentinel Wyrm
Miirym, Sentinel Wyrm copies every Dragon that enters, meaning the creature count needed for Klauth's Will's full effect is almost guaranteed — and the sweeper protects those Dragon tokens by clearing everything else.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | not legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Commander is where Klauth's Will lives — the format's singleton rule and multiplayer dynamics mean artifact and enchantment hate on a creature-sweeper is exactly the kind of flexible, high-ceiling card that earns a slot. Outside Commander, Klauth's Will is legal in Legacy, Vintage, and Oathbreaker, but those formats either have faster answers or don't support the Dragon-heavy boards the card demands, so it sees essentially no play there. In Oathbreaker, a Dragon or Dinosaur planeswalker-adjacent shell could unlock both modes, but the competition from purpose-built removal is stiff. Stick to Commander.

Price Context
Current price
$4.35 cheap tier
At $4.35, Klauth's Will sits in the cheap tier and delivers strong value — a modal sweeper with this much flexibility would cost twice that if it saw play outside Commander. It's a stable pickup with steady demand across every Dragon and Dinosaur deck in the format.
