And I also got a small question:
Can I activate Last Will Effect when Ohka goes to the graveyard at the end phase?

 

[Jathro]

Why Hyena over Nimble Momonga?

And to answer your question: Activate Last Will during one of your Main Phases. When Ohka sends itself to the Graveyard at the End Phase, you will get your search.

 

[Maruno]

Your End Phase is still part of your turn. Simply, yes.

 

[Oceanus]

But that's it, you search then, or not at all.

Why Hyena over Nimble Momonga?

I find to be more versitable in my case.
