"Questions that are answered in the rules" megathread

[Thaal Sinestro]

Also, I have this totally rad idea I want to do but the rules say I can't do it. Since I'm special, won't you bend the rules for me? Just me? If you don't bend them for anyone else, it's like they were never bent at all!

No, my special idea is more feasible and thus only I should have the rules bent for me. I can't find a way for the rules as they exist to suit my needs
