Leaving aside all the mechanics of the game, and focusing only on the setting and narrative. How do you justify the use of the OL deck?.
That is, the skills of heroes and monsters are held because the figure in question is there, but not so with the OL, who works in the shadows, who knows where. So how do you explain the effect as happened?
Cards like Dash or Frenzy, You can say that the monster brings a potion and drink it makes the effect. An effect like "Critical Blow" you explain the magic weapon that has the monster (effect of 1 single use), because this cards that act directly on them.
But in a card that affect the field or directly heroes, how they would explain?
Tnks and sorry for the bad english...
