Card Rulings:Wave-Motion Cannon

• Sending "Wave-Motion Cannon" to the Graveyard is a cost, so when you send it to the Graveyard, it's too late for your opponent to chain "Mystical Space Typhoon", etc., to destroy "Wave-Motion Cannon", because "Wave-Motion Cannon" is already in the Graveyard.

• Your opponent cannot chain "Magic Jammer", or use "Dark Paladin", etc., when you send "Wave-Motion Cannon" from the field to the Graveyard. Your opponent CAN chain "Magic Jammer" or use "Dark Paladin", etc., when you first activate "Wave-Motion Cannon" (meaning when you place it face-up on the field).

• If "Imperial Order" is active on the field, count Standby Phases as normal for "Wave-Motion Cannon".

• You can activate "Wave-Motion Cannon" (place it face-up on the field) and send it to the Graveyard during the same turn, but it will not do any damage.

• If the Standby Phase is skipped with "Solomon's Lawbook" or the turn is skipped with "Gamble", increase the count for "Wave-Motion Cannon" anyway.

• You cannot use "Pyro Clock of Destiny" with "Wave-Motion Cannon".
