Vault Notes & Play Impact

Keep two mana available to answer an eligible spell before it resolves. The first mode covers inexpensive spells regardless of color, while the second can stop larger red or green threats. Its mana-value limits leave some spells outside its reach, so it works best alongside interaction that covers those gaps.
