Special - Geralt is to decide who goes first at the start of the round.
The Scoia'tael is an flexible and relly interesting deck that requires a great deal of skill to play properly. Where the Nilfgaard and the Realms are truly straightforward and the Monsters are pure beast force, the Squirrels focus on combining debuffs that affect the enemy units like the Weather cards with a moderately strong assortment of units.
Units with Agility can be deployed in either the Close or Ranged combat rows, giving you tactical flexibility: Field a debuff against a strong enemy unit set, then counter with your own units in unaffected rows. Another advantage of the deck is that Geralt get to choose who plays first. While the AI usually chooses to be the first to play its cards, it's usually more advantageous to let the opponent play when you turn.
