So by 4/6 majority, no ubers will be allowed. If I RNG anything on the "uber" list, I shall redo it until I do not get an uber.
Since Arceus is uber, it will also be cast out in the same manner.
By a vote of 4/6, Species Clause will NOT be on. Getting the same non-uber pokemon number by the RNG will not cause me to redo the RNG.
Since the average of all the suggestions are 25.0833333333333333333......., we will use a pool of 25 pokemon to choose from after they have been RNG'd.
Thanks to the other five people who voted! =D
