To set up OMNIA:

​

• Shuffle your flavor deck, then shuffle it together with each opponent's flavor decks to make one "Shop deck" made up of everyone's cards. Make sure each player gets the opportunity to shuffle the shop deck! Once shuffled, set the shop deck in the middle of the table, within reach of all players. 

• Each player sets their source stack face up near by the shop deck, and shuffles their basic cards to make a starting player deck. 

• Randomly decide which player takes the first turn, often by dice roll-off or a similar method, then flip the top 5 cards of the shop deck face-up in a row to finish off the "Shop Zone". Once the Shop Zone is complete, each player draws a starting hand of 5 cards. 

​

Each player starts the game with 20 life, and a player deck with 2 basic hero cards, and 8 basic source cards.

​

Gameplay

 

In OMNIA, there are 3 phases of play, the Action phase, the Clean-Up phase, and the Draw phase, in that order. 

​
 

Action Phase

In the Action phase, each player has 5 actions they may perform, in any order, as many times as they are able. Those actions are Activate, Attack, Prime, Purchase and Play. 

​
 

Activate

Pay a cost and activate an ability of a hero, item, equipment or primed spell you control. Activate is the ONLY action players may perform during another player's turn, when they have priority. (See "The Prime Flow" for more details.) 

​

Attack

Hero cards have a set of additional statistics that other card types lack, Atk and Def. Using the Attack action, players may attack other players with a hero they control. To perform an Attack action:

• The attacking player declares the "attacking hero" , and the "defending player". 

• The defending player may then declare any number of heroes they control as a "defending hero". 

  • If no defending hero(es) are declared, the defending player takes damage equal to the attacking hero's Atk. 

  • If one or more defending hero(es) are declared, each hero deals damage equal to their Atk to the opposing hero. If more than one defending hero is declared, the attacking player may choose how to allocate the attacking hero's damage. 

• Once the attacking hero's damage is allocated, all hero's damage is applied. If a hero takes damage equal to, or greater than it's Def, that hero is destroyed. 

• If all defending heroes are destroyed, any remaining damage will carry over to the defending player (even if the attacking hero is destroyed as well).

• If an attacking hero deals damage to a player in this way (even if the attacking hero is blocked), that hero cycles and is put into its controllers discard stack. 

 

Since only heroes and players participate in combat, spells and abilities that target one or more combatants may target either players, or heroes. 

 

Prime

Some spell cards have the sub-type Prime. Prime spells may be placed face down on your play field to be used later by performing the Prime action. "Primed" spells may be activated any time you have priority with the Activate action by discarding a card from your hand, and flipping the primed spell face up. The spell is then Played, and goes to the Prime Flow to be resolved, just as if it had been played from its controller's hand. 

 

Purchase

Cards in the Shop Zone, both yours and your opponents, may be purchased by any player with the Purchase action. This includes any card in Shop Row, as well as any of the source stacks. 

 

Cards are purchased using source gained by playing source cards. Playing a source card is a special action, does not pass priority, bypasses the Prime Flow. Activated abilities that generate source however do pass priority, and may be responded too using the Prime Flow as normal. 

 

Once you have the appropriate amount, and flavor, of source, you then move the target card from the Shop Zone, to your discard stack, expending the source required in the Cost box. 

 

Once source is "gained" you have it until it gets spent, or at the next "Clean-Up Step"

 

Play
Cards in your hand may be used by performing the Play action. To play a card, place it face up in front of you in your playfield, and depending on the card type it will either:

 

-Enter play in your playfield under your control and remain there until an effect sends it to the discard stack (or some other zone) in the case of hero, item, equipment, and spells with the Enchantment sub-type; or

 

-Immediately apply the effect(s) described in its text box, and then goes to the discard stack of its controller in the case of spells.

​

Players may only play cards from their hand during their turn, when they have priority, and the Prime Flow is empty.

​

 

~The Prime Flow~

 

Whenever a player performs an action, that action goes to The Prime Flow to be resolved and applied. When an action is performed by a player, one at a time, each other player gets priority, starting with the active player and proceeding in turn order. When a player has priority, they may either add an Activate action to the Prime Flow, or pass priority. 

 

Once each player passes priority, the actions in the Prime Flow resolve and apply effects, one at a time, starting from the most recent ability added to the Prime Flow and working backwards to the oldest, or “First In, Last Out”. 

 

Players may not play cards from their hand while there are actions in the Prime Flow, with the exception of source cards to pay the cost for an Activate action.

 

Clean-Up Phase

 

After a player is done performing actions, they proceed to the Clean-Up Phase. During the Clean-Up Phase, the following happen in order:

• Each player receives priority.

• All players lose all unspent source.

• All Equipment cards not attached to heroes are sacrificed.

• Damage is removed from all heroes.

• Discard any cards still in your hand.

 

Draw Phase

 

After the Clean-Up Phase, draw a new hand of 5 cards, and the turn passes to the player to the left.

​

Ending the Game

​

When the first player reaches 0 life, the game ends. Each player will then:

• Gather the cards in their deck, discard, hand and playfield and count the  total the Prestige value of all the cards they have purchased and added to their deck over the course of the game.

• Add their remaining life total to the their deck's Prestige total to find their final score.

​

Whichever player has the highest final score after Prestige and life total is the winner!

​

Make sure each player leaves the table with the cards they come with! Card sleeves are not required, but recommended. Each player may have different color or style of sleeves from the other players, but all of YOUR cards have to be in the same color.
