Impulsivity
Creature — Elemental Incarnation
When this creature enters, you may cast target instant or sorcery card from a graveyard without paying its mana cost. If that spell would be put into a graveyard, exile it instead.
Encore 
(, Exile this card from your graveyard: For each opponent, create a token copy that attacks that opponent this turn if able. They gain haste. Sacrifice them at the beginning of the next end step. Activate only as a sorcery.)

Impulsivity lets you copy a spell and cast the copy for free — the payoff is immediate and substantial. The cost is a dead draw for the rest of the turn, which matters far less when Ashling, the Limitless is already threatening to end the game with an overloaded replicate chain.
Best Commanders
Commanders with the highest synergy
Ashling, the Limitless
Ashling, the Limitless runs Impulsivity because copying a replicate spell mid-chain can double a lethal board wipe or push Ashling's damage output past the threshold that kills the table — the free cast means you're not paying extra mana on the turn you most need to be tapped out.
Ashling, Rekindled
Ashling, Rekindled leans on Impulsivity to copy key instants or sorceries at the moment her triggers are stacking up, where the tempo of a free spell offsets the cost of skipping your draw step on a turn you're already winning.
Feldon of the Third Path
Feldon of the Third Path uses Impulsivity to copy high-impact spells in a deck already comfortable losing cards to the graveyard — the missed draw is almost a feature when Feldon wants the bin full.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | not legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Commander is where Impulsivity does its best work: the format's one-of rule means spell copying stretches your redundancy without adding duplicate cards, and the single draw step you sacrifice is a small price on a turn you're going for a kill. In Legacy and Vintage it's legal but uncompetitive — Fork effects with lower opportunity cost exist and see no meaningful play there either. Outside of 60-card formats entirely, Oathbreaker is the one other shell where Impulsivity occasionally shows up, particularly in spell-slinger builds where the free copy on a signature spell represents a genuine two-for-one.

Price Context
Current price
$0.34 bulk tier
At $0.34, Impulsivity is deep bulk — the kind of card you grab out of a box or toss into an order to hit free shipping. Bulk rares at this price floor rarely appreciate unless a breakout deck pushes them into the spotlight, so treat it as a throw-in, not a pickup for value.
