# Intervene Intervene is a common instant from Urza's Legacy that counters a spell and draws a card, making it a straightforward tempo play. Collectors view it as a functional utility card rather than a standout piece, though it represents the set's blue-focused design philosophy. The card's appeal lies primarily in its clean mechanics and role in limited formats of that era. For set collectors, Intervene serves as a necessary common to complete Urza's Legacy. The foil variant exists but carries minimal premium value compared to rarer cards from the set. Neither version commands significant collector attention, and both remain affordable and readily available in the secondary market. It's the kind of card that fills gaps rather than drives collection priorities.
