I made this card for fun. Heavily inspired by "In the Web of War", Lightning Flashes is the absolute red card. :D
And yes, the last sentence means a lot to prevent the abuse of the no mana cost to use the ability on the card. What can I say? I'm a genius. :D After all, I do have to prevent the phenomenon of infinite 2/1 trample, haste Elemental tokens as well as an infinite number of 2/1 blockers when needed.
