Live Dirge spell from Outlaws set working as intended?

Keyler

I was trying the Lively Dirge spell and seems only reanimate a creature if already was in the graveyard before casting the spell. If there is no creatures in my graveyard and this spell drop one of cost 12 or less (and I have done 2 or more gem´s combinations) the second part of the spell does not happens, but if already was a creature cost 12 or less before casting the spell, yes. With other spells with same text as Connive/Conncoct and Cauldron´s Gift works fine.
