I assume you can not use the token summoned from Reorigin as cost for Charge?
I really like Core personally. It is a card that can help out Shiranui Zombies immensely by choosing the order of what you want to banish with a bit more precision and at your own pace over other cards that have specific or delayed timings. Being able to summon out Linkuriboh doesn't actively help out Zombies a ton, but it is a utility that can't hurt.
Charge looks interesting. In Vendreads, it looks like it has real potential since it is the card they need to get precise levels and put whatever effects they want on the ritual monster. Not sure it has a ton of application for Zombie decks as a whole other than turbo-ing out Core. It does have similar problems as Brilliant Fusion if used as an engine and, unlike BriFu, is a minus. Is it searchable?
Haven't played Vendreads as a deck since their first wave of support, so I dunno if this trap or the Ritual monster is what they need.
