# High Alert High Alert is an uncommon from Ravnica Allegiance that appeals to collectors interested in defensive strategies and creature-focused decks. The card's ability to grant creatures vigilance and allow them to block as though they didn't have summoning sickness creates interesting deckbuilding possibilities, particularly in limited formats where it can swing games significantly. Collectors typically view High Alert as a solid uncommon with modest appeal beyond its mechanical function. The foil version exists but holds little premium value compared to other Ravnica Allegiance printings. Most interest comes from players building specific defensive or creature-heavy strategies rather than collectors seeking rare variants. It remains a straightforward uncommon without notable scarcity or special editions that would drive collector demand.
