Gonna point out the reason why he lacks most of his second key powers in his first one is because he does them through dream manipulation, and anyone can think them away.
For the suggested abilities:
I have already explained that he won't get other beings skills unless showed or stated to have them, so 3, 4, 5, 9, 10, 11, 13, 14, 15, 16, 17, 19, 24, 26
Several are just kind of non-factors, like 2, 8, 20, 21, 25, 29
Some are just wrong, like 6 (not weapon creation), 7, 9 (Mabel land doesn't manipulate your emotions. It just throws what you want in your face.), 13 (Dream manipulation), 22 (he isn't resisting it), 23, 27 (That is not what plot manipulatin is), 28 (Type 4 only applies if they ressurect whenever they die. This is not true for Bill), 30 (He wouldn't need to give up his pride and pray to axolotl if this were true. Not only that, but "his henchmen in disarrey" can easily stand for the ones not shot being in disarray because those they work with just died), 31 (He didn't create the concepts)
1 is fine.
