Judge's Familiar - Return to Ravnica (Uncommon) [RTR-218]

Judge's Familiar is a 1/1 Bird creature from the Return to Ravnica set with flying and the ability to sacrifice itself to counter an instant or sorcery spell unless its controller pays {1}. This makes it a valuable tool for controlling the battlefield, especially in decks that aim to disrupt your opponent's strategies. Its low mana cost and flexibility make it a solid choice for Azorius (WU) control or tempo strategies that rely on countering spells at critical moments.
