Spell Syphon⁣ - Shadowmoor⁣ (Common)⁣ [52]

Spell Syphon counters a target spell unless its controller pays {1} for each blue permanent you control, making it a strong choice in blue-heavy strategies. It can effectively disrupt opponents’ plays while gaining additional leverage based on your board state. However, its effectiveness decreases in decks with fewer blue permanents, as the cost to counter spells will be less taxing for opponents.
