Wizards of the Coast has designed a series of five new Magic: The Gathering cards for the Modern format through Modern Horizons 3, featuring rare spells that can be cast for free.

All five Flare spells in Modern Horizons 3 (MH3) are new to the format and have a rarity of Rare. Each of the five spells is Mono-colored, representing the five colors in MTG. Each Flare spell can be cast for free if the controller sacrifices a non-token creature of the same color. The mana cost of the five Flare spells varies, and all but Flare of Cultivation are Instant spells.

The abilities of the Flare spells work in conjunction with that MTG color. For example, the Blue Flare spell Flare of Denial counters a target spell. You can sacrifice a creature or pay the mana cost to cast an MH3 Flare spell. All Flare spells have a Retro Frame alternate treatment.
