Phantom Rework and Moon Cycle.

A while ago, Notch made the Minecraft sun and moon round, so he could presumably add a not funny-looking moon cycle. I was thinking if this was brought back, a lot of new ideas could come around, such as a Giant Phantom mini-boss spawning on a full moon.

This Giant Phantom flies solo (get it) and will swoop down and deal Warden-like damage to the player. Just like the Warden, this mob is seen as more of an obstacle and should just be avoided, but unlike the Warden, you can still go out of you way to kill it, gaining some Phantom Membranes for you efforts.

I think the problem with the Phantom is it's clunky flying mechanics and having to deal with multiple, small enemies attacking from all angles, kind of like flying Baby Zombies. Having one large, easy to hit target would feel much more like an Ender Dragon fight than just a swarm of little ankle biters.
