Swarmling Strain

Zerglings you cast have Replicate{r/g}
If you would create one or more Zergling tokens,
instead create those tokens plus an additional
Zergling token.
When Swarmling Strain enters, if you control
a Raptor Strain return that card to its owner's hand.
{2}: Put a Raptor Strain from hand onto the battlefield. Activate only as a sorcery.
