Banning should always be a last resort. While at first I was almost annoyed that Lysandre's Trump Card was banned while ignoring Seismitoad-EX, at this point the-powers-that-be should definitely wait to see how things evolve. Even if Seismitoad-EX still dominates the tell end of this format, rotation is so close that yet another ban seems like a really bad idea.
Now if after the rotation and the next set it still is dominating things then it may come to such a last resort.
