Rules of Acquisition" is an episode of the television series Star Trek: Deep Space Nine, the seventh episode of the second season. It is most notable for introducing the Dominion, although at the time it was unclear what the Dominion was. The Dominion first emerged as a story arc in the final episode of this season, "The Jem'Hadar".

My thoughts of this episode and on- -is that the Dominion should have had a bigger role than what they gave them. They should have been the next Clingons.Whats your thoughts????

I actually like the mysterious aspect since you hear only rumors about them then when they show up the go all badass of the Feds.

It also helps maker them more badass when the Fed ship they blow up is the same class as what was at the time the most recent Enterprise.
