Tornado, Frost and Monster Card (what system is?)

Hello guys,
I saw that monstercard.net, frostcard.net and tornadocard.com are the SAME system (just images change).

Someone knows which cms/open source they use for?
Ty!

why dont you just contact one of the owner of this websites and ask them ?

Because this is impossible xD is the same owner and he is owner of fantasygames, epicpb, epicdragonica, destiny lastchaos. Everything of them are secret xD
