If Alien Hypno is flipped face-down, do you keep the stolen monster?!
Alien Hypno has taken control of a monster and is flipped face-down by Book of Moon.
No. When Alien Hypno is flipped face-down, it loses its effect and the stolen monster returns. Flipping Hypno back up does not restore control.
If I Brain Control my own Alien Hypno, take Goyo Guardian, and then Brain Control ends, what happens in the End Phase?!
Alien Hypno is taken with Brain Control, its effect takes Goyo Guardian, and then Brain Control expires in the End Phase.
When Brain Control ends, Alien Hypno returns to its owner's field. Because Hypno is no longer on your field, control of Goyo Guardian returns to its owner as well.
