Acklay Counter can only be used once. Todd's response to #2 said "As long as there isn’t a limitation or another cost (like exhausting a card), you can use the same ability twice with this." Since abilities can only be used once during a timing instance, there is a limitation.

Pasi, can KDF work with Fluidity? Playing KDF as providing an additional token in the same timing instance would, but does the whole exhaust KDF after spending a token make a difference? If so, it provides another option for Tress.

I would play that you need 2 style tokens to use Fluidity (you're not spending 1 and then adding more, you are required to spend 2).

However, I would not get both Krayt Dragon Fury and Fluidity even outside of the app, so I would not have the issue...
