The artifact costs two, spends two, no tapping, and then puts the top card of your graveyard to the bottom of your library a brilliant mana sink and then way to trigger your stuff

This means that, by the time the opposing player forces Moltres ex out of the active Pokmon slot, there is often a Charizard ready to go with upwards of six energy attached, allowing it to essentially wipe out whatever is put across from it
It even gets around pesky abilities like indestructible, and it trades itself up for better creatures, which means it might be even better than the original chupacabra in some ways
