Keywords: Playing Dead Article

*Verdict -
Whenever you Verdict, the game will choose one Light Verdict and one Dark Verdict to present to your opponent. They then have to choose which effect will happen. One will be good for the player playing with the Verdict cards, the other will be bad for the enemy player playing against the Verdict cards (One Light verdict and one Dark Verdict). The effects are as follows:
Light Verdicts:

• Each opposing champion draws a card.
  
• Each opposing champion summons a Phantom.
  
• Each opposing champion summons a Daybreak.
  
• Opposing troops get +1 /+1 .
  
• Each opposing champion puts a random troop from their crypt into their hand.
  

Dark Verdicts:

• Discard a random card.
  
• Sacrifice a troop you control.
  
• Each opposing champion summons a Nightfall.
  
• Troops you control get -1 /-1 .
  
• Sacrifice an artifact or constant you control.
  

For each of these Verdict effects, the HEX client intelligently chooses ones which are relevant to your game. For example, if your opponent makes you Verdict and you don’t have an artifact or constant in play, you will not be shown the Dark Verdict choice to sacrifice a constant. Similarly, if your opponent doesn’t control any troops, you won’t be able to give their troops +1[ATK]/+1[DEF]. The Twilight Host will have you choose a different sentence instead.

*Momentum -
Momentum rewards you for playing resources. It says “When you play a resource, this gets +[ATK]/+[DEF] equal to the amount of Momentum this has until the start of your next turn. Then, its Momentum increases by 1.”

Thus, the first time you play a resource, Jubilant Jouster becomes a 2/2 troop until the start of your next turn. The second time you play a resource, Jubilant Jouster grows from a 1/1 to a 3/3! The Momentum keyword allows smaller troops to continue growing as the game progresses, as well as gives you something extra to do with your resources later in the game! In this case, it turns Jubilant Jouster into a really powerful threat with Crush who can’t be blocked freely by Candlekins or Phantoms. Momentum appears in Diamond, Ruby, and Wild, so be on the lookout for different combos you can unleash with this powerful new keyword.

*Portal -
Portal is a new keyword that appears on special portal cards. At the start of each of your turns, portals in your hand transform into a random card of the same rarity that you have the thresholds to play. Different kinds of portals have different rarities, so this can be quite powerful!
