If a spell's target becomes invalid (leaves the battlefield), does the spell fizzle? Does it still count as played for effects that trigger on playing spells?

Ruling: When a spell's target becomes invalid before resolution, whether it fizzles depends on the spell. Void Seeker still resolves and draws a card even if the target moves. Leona's signature spell fizzles if its target is gone. A fizzled spell still counts as played for effects like Red Darius that trigger on playing spells.

Nuances:

• Different spells handle invalid targets differently - some effects can still resolve (like Void Seeker's draw), while others fizzle completely (like Leona's signature spell)
• Even if a spell fizzles, it was still "played" and triggers effects that care about playing spells
