Myr Prototype enters as a colorless creature with modular power and toughness scaling — you pay X and get that much stat spread, effectively a blank body sized to your mana. The cost is exactly that: it does nothing else, no enters-the-battlefield effect, no keyword, no text beyond its own assembly.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Myr Prototype is legal in Commander, Legacy, Modern, Vintage, and Oathbreaker, but sees virtually no competitive play in any of them. In Commander it occupies a narrow niche: artifact-matters decks that need a colorless creature with a predictable size, or Modular- and counter-synergy shells where the X-cost body can grow with +1/+1 counter support. Legacy, Modern, and Vintage demand far more from a creature slot than a vanilla X-drop provides, and Myr Prototype has never made a dent in those formats.

Price Context
Current price
$0.18 bulk tier
At $0.18, Myr Prototype is deep bulk — the kind of card you pull from a common box rather than buy. Bulk artifacts with no competitive demand don't appreciate, so there's no floor to watch here; it's a penny-bin staple for the handful of decks that want it.
