A Pokmon 'Energy Card Break' is when a participant is assigned one of the eight energy cards, such as Fire, Lightning, or Metal, and then a pack of Pokmon cards is opened on stream once all 8 energy cards have been assigned, all the cards from the pack go to the participant assigned to that energy
First, it will amass Orcs 5, then will mill the caster for five cards to stock up the graveyard
If your opponent has no monsters on his/her side of the field, remove this card from play
Also something to note on the Himenos
TCGPCollector does admit that their experiment doesn't account for 'account hourglasses from missions and events', which can be a source of free packs, but that factor wouldn't likely make much of a dent in the day total
