Thran Dynamo card art
Thran Dynamo puts three colorless mana on the table for four mana — net positive on the turn you tap it, and it accelerates every subsequent turn. Pair it with Voltaic Key and you're generating five mana off two cards; in Bello, Bard of the Brambles it's also a free +1/+1 bonus stapled to that engine.

Commanders with the highest synergy

Bello, Bard of the Brambles

Bello, Bard of the Brambles

72.8% of decks · synergy 0.65

Bello, Bard of the Brambles pumps every artifact that enters the battlefield, so Thran Dynamo arrives as a 3/3 beater and immediately starts bankrolling the oversized spells Bello wants to cast — the 72% inclusion rate reflects that dual role.

02

Ashling, Rekindled

70.8% of decks · synergy 0.62

Ashling, Rekindled wants to spend mana fast and repeatedly, and Thran Dynamo provides the colorless cushion that lets her abilities fire ahead of schedule without straining the color sources.

03
Memnarch

Memnarch

64.1% of decks · synergy 0.51

Memnarch's activated ability is mana-hungry by design, and Thran Dynamo is one of the most efficient ways to stockpile the colorless mana it demands — the 64% inclusion rate across Memnarch lists says this pairing is essentially expected.

04
Ulalek, Fused Atrocity

Ulalek, Fused Atrocity

51.9% of decks · synergy 0.47

Ulalek, Fused Atrocity triggers cascade-style spell copying that rewards casting expensive spells early, and Thran Dynamo compresses that timeline by several turns.

05
Mishra, Eminent One

Mishra, Eminent One

51.3% of decks · synergy 0.47

Mishra, Eminent One copies artifacts at combat, and Thran Dynamo is a natural target — a copy means six free mana floating every turn the engine is live.

Commander is where Thran Dynamo lives; the 100-card singleton format's long games and high-CMC threats make a permanent that generates three mana every turn one of the most reliable accelerants in the format. In Vintage it's legal but essentially invisible — the format's broken mana rocks and one-mana accelerants make a four-mana investment uncompetitive. Legacy is the same story: the formats that allow it are fast enough that Thran Dynamo's cost is prohibitive, and Commander is the one context slow enough for that investment to pay off cleanly. Oathbreaker, like Commander, runs long enough that Thran Dynamo can shine, particularly in decks whose spells cluster at five or six mana.

Price Context

Current price

unknown tier

Thran Dynamo has been reprinted enough times that copies are widely available and typically land in the $1–3 range depending on printing — check current listings before buying since supply fluctuates with reprint products. At that price point it's one of the better value pickups in colorless ramp, punching well above its cost-per-impact ratio.
