Reliquary Box

The reliquary box is a rotating set of 20 cards which the user can pay to pick a card at random from.

Cards are not immediately replaced as cards are taken. This means that with enough picks you are able to guarantee taking all 20 cards from the box. The exception to this is that when the last card is picked, all 20 cards are refilled(with the same cards) and picks can start again. The box also refills when it rotates away.

Boxes are not shared, but are identical. I.e. everyone gets their own box to make picks from that refills when they empty it, but everyone's box rotates at the same time to the same cards.

Reliquary Tokens
Picking a card from the Reliquary box costs 10 reliquary tokens. These tokens can be obtained from the store for 80 gems for 10 tokens (i.e. one pick). However buying tokens from the store is the most expensive way to obtain Reliquary Tokens, at 8 gems per coin. They can also be obtained from reliquary token tournaments(3.3 gems, 1.7 gems or 1 gem per coin depending on how well you do), as well as randomly from gold, epic, arena and crew chests(all 1 at a time, for free).

Gems
Alternately, the option is available to "buy out" the box. At a cost of 70 gems per card, all remaining cards in the box can be picked at once. e.g. to buy a full box of 20 cards, this costs 1400 gems, whereas a box with 11 cards remaining would cost 770 gems. As with individual picks, when the box is emptied this way, the box will refill back to 20 cards again, allowing for further picks, another buyout, or combination thereof.

Rotation
Every 7 days, the cards in the box (regardless of how many are left) will be replaced with a new set of 20 cards, following a strict rotation of 12 sets. Each box is comprised of 2 copies each of 9 E Cards and 1 copy each of 2 L cards. Cards will always come up in boxes as the same rarity (e.g. an E will never show up as an L and vice versa). These 12 sets are split into two 6 set halves, with each L showing in one box in each half, and each E showing in two different boxes in each half. This gives a total of 12 unique L cards and 27 unique E cards.
