The Vault will open once youve gathered enough card duplicates and give you a reward in the form of three uncommon, two rare, and one mythic wildcard
It is said to bring happiness to those it meets, making it a beloved companion for trainers who cherish the sea
Basically as long as at least one card cares about a specific type, they will always exist
The infrastructure for bulk submissions in Japan is highly developed, costs are relatively low per card, and there is a strong cultural norm of grading even inexpensive cards as a matter of completion and collection display
In all other respects, it offers the same high quality build and styling of the Quiver, meaning your cards are just as well-packed and protected, only on a smaller scale
What that means is that your aim is to completely flood the board with creatures, and then just keep attacking until youve won the game
