Thought Experiment + Soft Rant:
Yeah, we hate that card (see other reviews).
Sadly, Wicked Athame cannot replenish the offerings (since there is nothing to replenish without the "uses" keyword).
But, "Ashcan" Pete can ready it, circumventing a major criticism of this card. The challenge for him is to control cards with doom, which is hard to achieve with access to just 5 mystic cards (1 or 2 being this one). Not even Fickle Fortune works. If somebody wants to pull this off with Pete, I think the charms form The Scarlet Keys are the only viable option: Ceremonial Sickle, Dowsing Rod, Onyx Pentacle, Hallowed Chalice all offer ways to place doom AND get rid of it again. Although... Pete would not really need to play them in the first place (good boy!) and they are not very action efficient. Which brings us back to square minus one: Why use action-inefficient cards to power a card that generates action (inefficiently)?
The only viable way I see to execute this is to start as Amina Zidane and Transfigure into "Ashcan" Pete.
But honestly, I think this card only exists to sorta kinda get the actions lost to Sin-Eater back. But for that purpose, I agree with the other haters: It is too expensive and/or should not occupy a slot (or at least an arcane slot, instead) and/or should omit the "you control" restriction.
