now i'm not sure if this is treated as a combo or not so if it int please tell me

required cards - valhala hall of the fallen, the agent fo creation venus, the agent of mystery earth, lost sanctuary or hyperion, archlord krysta

how it works

first depending on your hand either activate lost sanct or skip or ahead to the next part

activate valahala
special venus
get 3 MSBs out
normal earth (if you have hyperion in hand then add jupiter if not get hypeiron >_<)
sync earth with MSBs to get stardust
banish venus for hyperion
then speial krysta

with this combo/move you get a devasting field of stradust, hyperion, and krysta. stardust id the prtoecter, hyperion the destroyer, and krysta special summon stopper

so basicly this combo you get one mean field that alot of duelists will have a hard time to get around (i ahve pulled this combo off several times have actually thought to try and center my agent deck around this combo)

Not a combo but a move that's done and nothing more. Also why stardust and not Trishula or Scrap Dragon, you do know that when you drop Kristya both players cannot special summon right?
