Chipper Skipper (Evolved)

On Evolve - Look at the top 4 cards of your deck. You may put a follower that costs 2 or less from among them into your EX area. It costs 2 less to play this turn. Put the rest on the bottom of your deck in any order. Whenever a Mercenary follower is put onto your field, give it +1/+1 and Rush.
