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.

If a battle that’s being attacked somehow stops being a battle, it is removed from combat. Similarly, if its controller changes in the middle of combat, it is removed from combat.

Only creatures controlled by a battle’s protector can block creatures that are attacking that battle. This means a Siege’s controller can never assign creatures to block for it.
