About this game
RELIQUARY is an online trading card game about the moment you can't afford everything.
You'll recognize the board: monsters standing in attack or defense position, spells and artifacts set face-down, heavy hitters paid for with tributes. What's different is the mana. You start a duel with 3 and gain 1 each turn up to a cap of 10, and almost every effect costs some. So the question is never only what you can play — it's what you're willing to spend, and what you're leaving yourself unable to answer.
Every effect has a price
A hand full of answers is worthless if you can't pay for them. Mana turns every turn into a budget: commit it to the big play now, or hold it back for the response your opponent is walking into. Your hero card has a once-per-turn ability that wants a piece of that same budget.
Over 1000 cards, all of them earnable
Multiple archetypes with gameplans of their own, a wide pool of standalone cards to build around them, and a lot of Reliquaries — Extra Deck bosses that only come down once you've met the condition printed on them.
Packs are bought with currency you earn by playing. And if the packs won't give you the card you need, dismantle what you don't want and craft it directly. There are no purchases on top of the base game.
Duel online — or take your time
Matchmaking puts you against other players, with matches resolved on the server so the rules work the same way for both sides. When you'd rather not queue, five AI opponents with decks of their own are waiting, and five preconstructed decks give you something to duel with from your first minute.
In the deck builder
Filter and search the whole pool, see at a glance what you own and what a missing card would cost to craft, and find out that your list breaks the banlist before you queue rather than after.

A note on Early Access
RELIQUARY is in development, and I'm building it on my own. There's a feedback button in the main menu that goes straight to me — balance, card wording, bugs, or a card you think should exist. That's how the card pool and the banlist are going to keep moving.
