Multicolored (also "multicolor", "multi-colored", "multi-color"; as opposed to "monocolored", "mono-colored" "single-colored") cards were introduced in the Legends set, and use a gold frame to distinguish them from mono-color cards. These cards require mana from two or more different colors to be played. Multicolored cards tend to combine the philosophy and mechanics of all the colors used in the spell's cost; examples of such cards are Quicksilver Dagger and Niv-Mizzet, the Firemind, which combine blue's ability to draw cards with red's ability to deal (direct) damage ("pinging").
More recently, two-color "hybrid" cards that can be paid with either of the card's colors (as opposed to both) were introduced in the Ravnica set. Hybrid cards are distinguished by a gradient frame with those two colors. Multicolored cards tend to be proportionally more powerful compared to single-color or even hybrid cards, because of the restriction of having to play all the colors in the casting cost.
