Mind Harness steals a red or green creature for a single blue mana, but you lose it the moment you tap out — the enchantment falls off if you can't keep up the upkeep. Narrow color restriction and ongoing mana tax make this a curio rather than a staple.

Where it lives, where it can’t
| Format | Verdict |

In Commander, Mind Harness is a niche include at best — stealing a green mana dork or red haste threat for one mana sounds efficient, but tying up blue mana every upkeep is a real cost in a format where you need that mana for interaction. Legacy and Vintage have access to it, but Control Magic effects with no strings attached exist and see no play, so Mind Harness isn't competing there either. The color restriction to red and green creatures is the final nail: too many threats it simply can't touch.

Price Context
Current price
$0.34 bulk tier
At $0.34, Mind Harness is deep bulk — you're paying for cardboard, not power. Don't expect that price to move; the card has no competitive application driving demand.
