4 DCEs, at least 2 PPs for me. Its the game-breaker in my opinion. Compared to Terrakion as a 3 or 4 card tech, I rather add consistency or other techs which can be used in more than one match up. Almost all (if not all) winning lists did not run any Bulls, and while some did I'm sure they did well with it, but a ZekEels does not at all require a Terrakion as a staple. The mirror is pretty much decided either with a traditional Mewtwo war or who can starve the other out of Eels or attackers. I would think Terra's main use was as a a direct Zekrom EX counter, and was great at it but decline in play of the Big Black Dragon doesn't give much reason to call on it as a need anymore.
