Silverquill, the Disputant

Silverquill is a 4cmc 4/4 flying vigilance elder dragon that grants every instant and sorcery you cast casualty 1, turning any spell into a potential two-for-one by sacrificing a creature with power 1+. It is a signature spellslinger-aristocrats hybrid commander: you want a steady stream of small creatures (tokens ideal) to sacrifice for doubled spell value. The vigilance body also attacks and blocks freely. It is solid but not format-defining, as the casualty cost requires consistent creature fodder and the payoff is conditional on casting instants/sorceries.

• Casualty 1 granted by Silverquill triggers a copy of the spell, not a second cast — this means it does NOT trigger prowess or storm count, and the copy is not a cast event.

• Token producers that make 1/1 creatures (e.g., Lingering Souls, Raise the Alarm) are especially synergistic as they both fuel the casualty sacrifice cost and can be doubled with casualty themselves.

• Silverquill's casualty applies to ALL instants and sorceries, so high-value spells like Demonic Tutor or Damn become extremely powerful with a free creature sacrifice — building around sacrifice-ready fodder maximizes his ceiling.
