The Idea is to get
Rilgon's Disciple big, flying and berserk. With 7 Attack he will deal 28 Damage. The other great finisher is
Geomar, the Steel Tempest. Give him Berserk and cast a ton of cheap spells from
Acquisitive Crow and BOOM. Otherwise every other creature can do a lot of work, too if you buff it up =)
Its super fun because you get a lot of random cards from
Acquisitive Crow and you can sometimes win very fast and quite often an almost lost game turns around quickly.
Unstable Form can also do a lot of funny things. Won me countless games. You can use it on your own creatures especially
Shelterwing Rider without Aegis. Use it to get rid of enemy flyers or combo creatures. Use it to get a 4+ creature for
Vanquish with a little luck. Use it to buff Geomar thanks to Echo. You can also get one extra if you draw it again with
Second Sight. Seems like a card that requires luck but its surprisingly consistent.
