Semi-staple

Semi-staples (similar to staples) are cards that are splashable, and can easily be used in almost any Deck, but are not always recommended. Most semi-staple cards are considered Side Deck staples, due to their overall flexibility, thus making them common, but not exactly synergistic with most Main Deck cards.
