thundahhhhhhhh

Lightning Sparkeel just kind of confuses me, if it's destroyed by an effect while your opponent controls it, who takes damage?

Storm Brewing is a nice idea but may be trollsome with the Eccentric or Thunder Ball cards.

Thunder Blast Archfiend and Stonehenge make lightning lock a new deck.

A big fat YES to Galvanic Soul Diety.
