"I'll sacrifice one of my Numbers to gain 2 stars, then play two Nanite Swarms. I then discard The Hearts III to gain 11 Hearts and then sacrifice my swarms, giving my lamb a total of 12 Hearts! I'll follow it up by giving it Divine Strength!"
"I also gain 2 stars from my swarms secondary effect and take 4 damage."

(While not really an issue here, I don't think facedowns can be selected as effect targets. Something for later given you have to bypass 21 hearts and a Shield to win.)
[Swarm needs a nerf badly.]
