2 rulings from Wizards of the Coast
- 4 October 2004The decision to counter a spell or destroy a permanent is a decision made on announcement before the target is selected. If the spell is redirected, this mode can't be changed, so only targets of the selected type are valid.
- 8 June 2016Pyroblast can target any spell or permanent, not just a blue one. It checks the color of the target only on resolution.
