Mental Discipline trades a card and two mana to make a land drop and cycle away a dead card — modest upside, real cost. It's a late-cut from most Commander decks because two-mana cantrips that don't replace themselves cleanly are rarely worth the slot.

Mental Discipline is a Pauper-playable card that sees essentially zero competitive play there — the format has cleaner filtering at the same cost. In Legacy and Vintage, it's outclassed by essentially every blue cantrip ever printed. Commander is where the argument is strongest, specifically in landfall or graveyard-recursion builds that can extract double value from the discard, but even there Mental Discipline competes against a long list of more efficient options.

Price Context
Current price
$0.11 bulk tier
At $0.11, Mental Discipline is deep bulk — you're paying for cardboard, not utility. It won't appreciate; supply is high and demand is narrow, so pick it up freely if a specific deck calls for it and don't think twice about the cost.
