Q: "Swarm of Rats" has power equal to the number of Rat cards the owner has in play. Do the 1/1 Rat tokens summoned by the "Lab Rats" card add to the power of the Swarm?

A: Any rat token or card labeled with "Summon Rat(s)" counts as a rat. Any effect that is affected by rats is affected by all rats. Note that the Fifth Edition card "Plague Rats" only counts other "Plague Rats" and thus would not count a rat token. "Swarm of Rats," however, would count a rat token.
