Unless of course, its only given to us in Full Art form....
There's no FA Karen in Japan...
Couldn't Karen be 104/114 or 105/114 because at most we get 8 fa's (Ranger,Garde,M Garde,Volcanion,Steelix,M Steelix,Magearna,and Sycamore) which will be 106/114 to 114/114 leaving two spots for Ranger and Karen... Did I miss something?
...And it's not in the set because Karen is too recent, in fact, it hasn't been released in Japan yet. The Trainer/FA line of Steam Siege goes pretty much like this:
98. Armor Fossil
99. Captivating Poképuff
100. Claw Fossil
101. Gardevoir Spirit Link
102. Greedy Dice
103. Ninja Boy
104. Pokémon Ranger
105. Special Charge (it won't probably change its name in english)
106. Steelix Spirit Link
107. Volcanion-EX
108. Steelix-EX
109. M Steelix-EX
110. Magearna-EX
111. Gardevoir-EX
112. M Gardevoir-EX
113. Pokémon Ranger
So, the only space left is:
114. Professor Sycamore
