If Rivalry/Gozen is active and you take control of a monster of a different Type/Attribute, what happens?!
You take control of an opponent's monster while Rivalry/Gozen is active.
If you control no face-up monsters when the effect resolves, the taken monster is not sent because there is no reference Type/Attribute. If you do control a monster, the conflicting monster is sent.
If Tragoedia targets my monster and I Book of Moon it, is it still taken?!
Tragoedia targets a monster and Book of Moon is chained to set it face-down.
No. Tragoedia cannot target face-down monsters, so the target is no longer valid and control is not taken.

●You gain control of the targeted monster in the same Battle Position that it was in on your opponent’s side of the field. If it is face-down you may Flip Summon it and any Flip Effect is activated. During your End Phase it is returned to your opponent’s side of the field in the same Battle Position as you last had it in. So if you attacked with the monster and it remained in Attack Position, it will return to your opponent in Attack Position.
●You can use the monster you control through the effect of Change of Heart as a Tribute for a Tribute Summon, or for an effect like Cannon Soldier’s.
