Light Cannon's skill is pretty neat,
requiring a group of cards/creatures to activate a skill is fun.
but in elements, you can only have 6 same copies of a card,
you will have to burn half of your deck to get 3 Light Cannons,
and then your opponent destroy 1 of your Light Cannon
it makes Light Cannon skill really difficult to cast to the point that
Light Cannon's skill is as good as nothing.
