Mix-and-match

Mix-and-match cards are cards that have two or more different named mechanics on them.

Normally when R&D talks about mix-and-match, they don't focus on cards with multiple evergreen keywords, as that's just something every set does. The more interesting mix-and-match cards are ones where neither mechanic is evergreen. These are hard to do because it requires having two mechanics in the same set that can work together on the same card. Of those in regular sets, cycling tends to have the most mechanical overlap and as a deciduous smoothing mechanic.

The first such printed mix-and-match cards appeared in Future Sight. They also appeared in Modern Horizons and Modern Horizons 2, and one or two others in sets with cycling.
