Knight of Obligation enters as a 2/4 with vigilance and extort — a defensive body that drains the table every time you cast a spell. Four mana for this statline is fair, not exciting, and it earns its slot only in dedicated extort or lifegain-matters shells.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |

Knight of Obligation sees essentially zero play in competitive formats — Modern, Legacy, and Vintage have no interest in a four-mana 2/4, and Pioneer has faster, more impactful options at every point on the curve. Commander is where Knight of Obligation has its only real argument: extort stacks across multiple permanents, and in a white-black lifegain or drain deck the incremental life swings add up over a long game. Outside of that narrow archetype, there are stronger vigilance creatures and better extort bodies available, so it remains a fringe inclusion even there.

Price Context
Current price
$0.15 bulk tier
At $0.15, Knight of Obligation is pure bulk — you're not buying it for value, you're buying it because it fills a specific extort slot for almost nothing. That price is stable at the floor; don't expect movement in either direction.
