Here's a deck type that most people probably haven't tried; a deck built on forcing players to pay costs for everything they do. This deck is not about conserving resources, it's about dropping everything to the board behind chain energy and letting your opponent agonize over what to do. This build is unique in the fact that it doesn't really have any set requirements as to which cards must be run in it, with the obvious exception of chain energy. I've been playing Chain Energy for quite a while, and though I've had both good and bad experiences with the deck, all of my duels with the deck have served to remind me how much I love this game. Here's a link to an example duel that I've played out with Chainergy, as I call it.
