I think a Wandering Monster is a random 3-cost minion, not one from your deck. I also think they are adding "monster" minions who will have good stats for their cost with a drawback of some sort to synergize with the recruit mechanic they are adding. I also think they are going to create a mechanic based around filling your hand with bad cards for benefits so you can take advantage of the full hand like with cards that replace your entire hand with (hopefully) better cards like Liilian Voss, the Golden Kobold, and Renounce Darkness.
