I really want to see how this fits into the next war for team death.
The card would likely be used more by other elements to gain easy access to cards.
I believe that is most likely true and I do not understand how vaults are put together ( never looked into it ) I think that due to card limits this could be very to use in certain decks. I could see this being of use to death, it might make certain cards a little better.
What would be some early war decks we might see based off what we know right now? I am very interested in it.
I imagine Entropy team could easily use it to fuel Bonewall deckout or poison stall. Together with other CC entropy has it would be extremely hard to break through. Same can be said for Fire or Air. Fire could easily mix it in a rush too.
Funny enough, Death team would hardly be able to use this same tactic due to Vault limitations. Also considering Death decks would already use bone pillars, and the fact that CC available to Death is terribly slow, I'm thinking this card would be useful more as pillar replacement, than for producing some epic new tactic. Fractal BoLs with fractal death creature deck could be decent though, didnt try it yet unupped.
