Koris

The Spiders are basically the 4th Human team (after the Syphr and two true human teams) with the unique benefit of their ability to create portals

Pros

 * Only team with the Portal ability
 * Has all three roles
 * Guards have Gotcha
 * All abilities are average

Cons

 * All abilities are average
 * Only 1 Striker, 2 Guards

Portal Placement
The Koris start with a portal in play which has to be on their side of the pitch. An excellent place for this is adjacent the mid-line as, once a second one has been deployed in the enemy pitch, it provides a speedy way to get deep into the end zone.

Ideally you want your 2nd portal adjacent the enemy 4-point strike hex. That way you increase the threat of being able to rapidly secure 3-point shots each turn (or even 4 points if the Keeper is removed).

Guards (S1)
With only a pair of Guards, the Koris quickly evolve towards them becoming specialists. Both should roll on the S1 table until one gets Keeper, then start to make the other one into your beatstick to deliver pain supported by your Jacks.

Jacks (S1)
As the majority of your team, and the only members able to create Portals, Jacks are your bread and butter for pulling off the tricks of this team.

That said, like most average teams, it will be the Guards and Striker who will be gaining most of the XP to develop themselves. Should a Jack get lucky and develop themselves, use the S1 Table to improve your player's versatility.

Strikers (S1)
With only a single Striker, you want to make sure he is worth his value. Use the S1 table to avoid Showoff and try to gain 3+ skill to make excellent shots, or Safe Pair of Hands to increase your chances of catching a throw.

Team Progress
Your Striker will need to improve his survival, so aim to buy +1 Coaching dice each game so you can try to improve your point-scoring-star with the Extra Training table. Even if he doesn't gain XP to level, the extra dice will help.

As soon as you can afford it, buy a second Striker to reduce the preasure off of having only one star-shooter.

Beyond that however, the team has no significant weakness or control of their progress. Build the team as you see fit based on how their XP develops them!

How to Counter
The Koris have a notable weakness in having only a single Striker. While they do have Jacks, they typically don't want to rely on them for making shots. So try to dogpile their main scorer as quick as possible to take him out of the game as long as possible.

Otherwise play to your strengths. With average stats across the board, use your Team's speciality of bashing or scoring to play their generalist style.
