Synergies with Sisyphus

Just a question. If Eurytheus Chose Sisyphus as his "Labor" and Sisyphus can't die....isn't Eurytheus unkillable as well? And if Sisyphus dies, does he triger, for example, Hades "Sould Culling"?

Sisyphus die and then rebirth so after his death Eurytheus loose his connection even if Sisyphus come back. Hades does triger Soul Culling when Sisyphus die.
Hades and Sisyphus in the same Team could be nice indead =)

Good, I was just wondering how Eurytheus Acts, but that makes sense, so the only way to make him "unkillable" is by using Chirons power.
Or Persephone. You can imediatly redraw a Card....imagene an underworld Team which has Hades and Persephone with Sisyphus  on their side....back that up with some fast dieng troop (Centaurs or Hounds) and maybe with some troop destroying Units (Circe or Minos)...
That could end up beeing a tought fight...

Sisyphus can die - he just comes back again. As Garshell says, his death would trigger any effects a unit's destruction normally triggered, and then you'd put him back to do it all over again
