Wrong expectation.

It certainly hasn't been asked! I'll explain in order (left to right, top to bottom):

"The power to learn future events through riddles": Each day, his book will provide him with 3 riddles that correlate to 3 different events that will surely happen in the chronological order of morning, noon, and night. He will need to decipher these riddles to learn of the future. Interpretation matters, but he can be absolutely certain the events will happen.

"The power to create and control toys": Anything stabbed by the pointy tip of his flag pole will turn into toys. Furthermore, he can animate and control these toys at will. Wounds suffered from him stabbing you with the pointy tips are absolutely deadly because your tissues will turn into toy blocks.

"The ability to control and monitor through insects": He can control insects and see through their eyes. Despite sounding quite bland compared to others, this ability lets him see the battlefield in a broader range, communicate with allies (controlling the insects to create Morse codes), and most importantly, stalk and learn the other players' identities to strike when they are untransformed.

"The ability to turn yourself into anyone": He can perfectly transform himself into any living organism he has seen before. Mimicking animals requires full transformation, while mimicking humans can be more versatile, as he can transform only certain parts of himself (faces, hands, etc...)

"The ability to grow plants": As the description implies, he can grow and control plants.

"The ability to travel into flat rectangular surfaces": He can phase into any flat, rectangular surface and hide in a pocket dimension. He can exit through any other rectangular surface within a range of 100 meters around the point of entry. His power also includes several floating, indestructible canvases around him. In battle, he hides parts of his body inside these canvases, meaning he would look less "naked" like in the design.

Quick fanart I made for a fursuit design that I really, really like.
