 * Tower of Heaven: "Heaven's Game was just a way for him to spend his time." He could have read a book or something, rather than risking his entire plan for a bit of amusement. The really intelligent person would try to minimize risk as much as possible, not just to the point of it barely being enough.
 * Nirvana: "He had amnesia,how could he know Brain was the one who taught him?" The amnesia didn't reduce his knowledge about magic or his intellect, so he should have known that the circle can be undone even without the pass-code. A really intelligent person would have formulated a contingency, just in case someone with the necessary knowledge came along.
 * The Timetravllers: Let's see how many people were aware of any future people coming back: Hisui and probably Toma, Archadios, Jellal, Meredy, Ultear, Natsu, Lucy, Mirajane, Yukino, Happy, Carla and Pantherlily. Everyone else only learned of future people and timetravel after the Dragons had come and gone.


 * Hisui, Toma and Archadios were busy with the GMG, Datongs interference and preparing the Eclipse Cannon for the Dragon Invasion.


 * Lucy, Yukino and the Rescue Team were busy with not getting killed.


 * Which means that the three CS members were the only ones who had the necessary information, time and lack of other things to do for figuring out this mystery. Not exactly a great proof of Jellal being a genius.


 * Dragon Invasion: Future Lucy told Jellal that her timeline was ravaged by Dragons and then the King told every mage in the city that the Dragons are going to invade, so was it really such a great deduction that soon Dragons would appear and that another Dragon Slayer would come in handy?

Yes, Jellal isn't a dumb-ass, but neither is the a super-genius, or the most intelligent person in FT. Put him up against people like Mavis and Levy and his intelligence is a bit lacking in comparison.
