Union Team Overview
The variety of choices within the Union combined with the large number of players makes the Union one of the more difficult teams to fully grasp on the table. It's possible to put together a Union team that can dish out nearly as much damage as the Butchers, then play a different union lineup in your next game which scores goals and maneuvers nearly as fast as the Fishermen. It's possible to play a game with a lineup that dishes out up to 3 different conditions in a turn (Bleed, Poison, Knockdown), and also leaves clouds of smoke on the table to provide cover. The magic to the Union comes with deciding which tactic to take then insert the requisite team members to build out a team to deliver.
One of the largest differences I see between the Union and other guild teams is how it approaches synergy. On other teams the players tend to have abilities that combine together to strengthen one or two players on the team. This creates strong combo's across a whole team, where each team's player combined to form a greater than the sum result. The union is exactly the sum of it's parts (players). I find combinations of plays within the union are fairly straight forward additions of each individual player to reach a desired result. On most teams there are lynch pin players who can be taken out to break apart a strong combo, but those players are often tough to get to, or tough to take out. The Union suffers from a situation where each player contributes exactly what they contribute, minimizing the risk of a lynch pin player, but reducing the overall team effectiveness as players are taken out. There is not really a quick drop of a set of plays stopping to work, but a gradual weakening of the entire teams play style.
This effect of an overall weakening vs lynch pin play can be a boon and a curse for union players. In a situation where the union player knows the roles of each of his models intricately it becomes very tough to stop that player from achieving his/her goals. There is not really a place to maximize efforts to reduce that players success in the game, but you have to wear them down over the whole game. In the converse situation where the player is not yet familiar with what their team does, the whole team will not work well. The Union team becomes clumsy and each of the model's can tend to get in the way of each other, hampering a final positive result of play combinations.
Let's take a look at the individual players and their roles on the field.
