A Siege’s controller can’t be its protector. If a Siege’s protector ever gains control of it, they choose a new player to be its protector. This is a state-based action.
Invasion of Ikoria // Zilortha, Apex of Ikoria
Battles can’t attack or block, even if one also becomes a creature. If an attacking or blocking creature somehow becomes a battle in addition to being a creature, it is removed from combat.
You decide whether to assign a non-Human creature’s combat damage as though it weren’t blocked just before it assigns that damage. You may make a different choice for each non-Human creature you control—that is, you may have none, some, or all of those creatures assign combat damage as though they weren’t blocked.
