I removed Lightnings and added 3 pillars and 1 Psion. It's ok, it's faster, but it goes in troubles against some decks and some creatures like devourer, dune scorpion, virus, toadfish, chrisaora, scarab, cruseders, ecc.. that's why i prefer the lightning version, you can kill enemy creatures that can give you problems or use it against your enemy to kill him faster if you need it!
