The goal is to sacrifice a persist creature infinitely to Altar of Dementia to mill our opponent's entire deck, causing our opponent to lose when they draw a card on their draw step
You could even opt for Pokemon stickers to seal packaging or use deck loaders from Elite Trainer Boxes or other Pokemon-branded sleeves

If you have more Prize cards remaining than your opponent, and if this card is attached to an Evolution Pokmon that doesnt have a Rule Box (Pokmon , this card provides every type of Energy but provides only 3 Energy at a time
That said, unless you are planning on opening a lot of boxes (to help even out variance), I'd probably plan on getting the non- Masterpiece value and treat the possibility of opening a super-sweet, super-expensive Invocation as a bonus lottery ticket that you get for free when buying a box of Amonkhet
