Fiery Cannonade reads:
Fiery Cannonade deals 2 damage to each non-Pirate creature.
Golden Demise reads (among other text):
All creatures get -2/-2 until end of turn.
I noticed that both could easily be rewritten to be consistent:
Fiery Cannonade deals 2 damage to all non-Pirate creatures.
Each creature gets -2/-2 until end of turn.
Is there a reason for the difference in wording, or any edge cases where the difference in wording would matter? MTG is usually high consistent for clarity, is this difference simply artistic choice of the writers?
