What it does
Spree is an additional cost mechanic found on instants and sorceries. When you cast a Spree spell, you must choose at least one of its "plus" modes, and you pay the listed extra cost for each mode you select. You can pick multiple modes if you can afford them, stacking effects in a single casting. The base spell often does very little or nothing on its own—the modes are where the power lives.
The common mistake: you must choose at least one mode, but there's no maximum beyond what you can pay for. Also, mode selection and cost payment happen as you cast the spell, locking in your choices before anything resolves. Each chosen mode's targets are also locked in at cast.
In Commander, Spree shines for flexibility—one card scales from cheap removal to a game-swinging blowout, and the modular targeting lets you split effects across multiple opponents or threats.
