I caught both. I had 2 Friend Balls so I ended up tossing one at Iron Leaves, with the other being reserved for whenever the heck the Rillaboom raid is.
Joined a Raid for Walking Wake and caught it in the Beast Ball you get for registering all 400 Pokemon, as I would probably never use it otherwise anyway =P
I don't really like Walking Wake. Iron Leaves is lackluster to me, but I don't dislike it.
I'm pretty much about to head to bed as I keep getting distracted and forgot to read this till now as a result lol

How's your availability tomorrow or Sunday?
