[Magic: The Gathering] I’m a planeswalker and I usually summon the legendary Kumena, tyrant of oracza to command my merfolk army. Am I summoning the actual Kumena or am I creating a copy from my memory. What about the other legendary creatures in my army?

It's a copy. With legendary creatures, there's a bit more to it than just forming a random merfolk and the copy goes a lot deeper to get their memories, but it is still clearly distinguishable from the original.
