The Commander

Flying, haste

Whenever Klauth attacks, add X mana in any combination of colors, where X is the total power of attacking creatures. Spend this mana only to cast spells. Until end of turn, you don't lose this mana as steps and phases end.

Guide

Gameplan

Cast Klauth, swing, and convert your attacking creatures' total power into a flood of mana that pours into giant haymakers the same turn. Each turn you ramp into Klauth early, attack to refuel, and chain big creatures, X-spells, and burn until something lethal lands. The deck snowballs hard — one good attack often produces 20+ mana to chain spells with.

Strengths

Explosive mana generation that can produce huge amounts off a single attack
Flying haste means immediate value the turn Klauth enters
Rewards going wide AND tall — any power on the battlefield fuels mana
Gruul has cheap ramp to deploy Klauth on turn 4-5 ahead of curve

Weaknesses

Heavily commander-dependent; loses tempo to repeated removal or recast tax
Mana only works on attack, so it's useless on defense or stalled boards
No card advantage engine baked in — can run out of gas after dumping mana
Color identity lacks counterspells and efficient interaction

Key Cards

Xenagos, God of Revels — Doubles Klauth's power on attack, supercharging mana output and adding haste to the team.
Apex Devastator — Cascade four times is the perfect mana sink to chain off Klauth's attack mana.
Selvala, Heart of the Wilds — Massive ramp and the kind of mana dork that survives to keep enabling explosive turns.
Crucible of Fire — Anthem for Dragons raises attacking power, directly increasing Klauth's mana.
Surrak Dragonclaw — Gives your fatties haste so they can attack and add to Klauth's mana the turn they land.
Vandalblast — Cheap artifact wipe and a good red sink for the mana Klauth generates.

Upgrade Path

Add fast mana and reliable ramp (Sol Ring, Birds of Paradise, Cultivate, Bloom Tender) so Klauth arrives turns 3-4, then include untap/extra-combat enablers like Aggravated Assault or Savage Ventmaw for explosive loops. Prioritize mana sinks that don't require attacking — big X spells, cascade payoffs, and Craterhoof Behemoth — and lean on protection like Heroic Intervention and Lightning Greaves to keep Klauth swinging through removal.

Dragon Tribal — A board of high-power flying Dragons generates enormous mana and synergizes with Dragon payoffs.
Combo — Effects that untap or grant extra attacks turn Klauth's mana into a near-infinite engine.
Spellslinger / X-spells — The colorless-into-any-color mana fuels big X burn and draw spells in one turn.
