This is a really strong card, especially because it can be used as removal, too, by declining to pay the energy
When you cast a spell with offering by sacrificing a permanent, generic mana in the sacrificed permanent's mana cost reduces only generic mana in the spell's total cost
Unlikely, but its still a decent card that has a 50% chance to pay back the mana spent on it even if your opponents never pass it again
