Murky vs Muradin
Murky can lane against Muradin. A huge part of doing this successfully is doding Muradin's hammer. Running around in circles around Muradin will make it harder for him to connect.
Once you get Fish Tank the fight becomes more fair. Muradin has his escape though so it will be rare that Murky will actually kill Muradin. If Muradin connects with his hammer stun that usually means Murky still dies.
