How to play
Two players, 20 HP each. Every turn runs Setup, Action, Cleanup: refresh your Reserve and draw, play cards and attack, then statuses tick. Your Main Deck feeds your hand and your Reserve. Your Nexus Deck holds the Legends and Wishes you play straight from it.
A Main Deck of 30 to 50 cards, up to three copies of each, and a Nexus Deck holding your Legends and exactly three different Wishes.
Your spent Reserve turns face-down, the top card of your deck joins your Reserve, and you draw. Then both players may set Traps.
Flip Reserve cards to pay for creatures, Equipment, Arenas, Legends and Wishes. Attack in this phase too: there is no summoning sickness, and the defender names a blocker or takes the hit.
Ignite, Poison and Frostbite deal their damage, Frozen creatures thaw, and a hand over 10 cards is trimmed at random.
Both players start at 20 HP. Bring your opponent to 0. An empty deck never loses you the game, but every draw from it hurts more than the last.
Two decks, built together
Creatures, Spells, Traps, Equipment and Arenas, at most three copies of any card. You draw from it, and its top card feeds your Reserve each turn.
Exactly three different Wishes, plus as many Legends as you like, one copy each. It is never drawn from: you play straight out of it.
The player going first draws 6, the player going second 7. Up to three mulligans, then each player puts 2 cards into their Reserve.
Seven kinds of card
Played into one of your five Army slots. Each has ATK, Max HP and up to two of eight subtypes. There is no summoning sickness, so a creature can attack the turn it arrives, once per turn unless its text says otherwise.
Four types and a wild card
You pay with your Reserve. Each turn the top card of your deck joins it face-down; to pay a cost of 3 Gold, flip three face-down Gold cards face-up. Spent cards turn back at the start of your turn, and killing an enemy creature refunds you. Some cards also ask for HP.
Mages and Elementals. Ignite, Freeze and the Rune Spells.
Beasts. Wolves, bears and Primosaurus, built to attack and Overrun.
Draconics, Warriors and Swords. A Golden unit is worth double when it dies.
Machines from the future, which Recycle and Resurrect each other out of the Archive.
Wild both ways: a Universal card pays any cost, and a Universal cost takes any type. Angels, Demons and every Wish.
