Hirluin the Fair is a EPIC hero! He is nothing without Outlands cards but those are so good I could put them in any deck even without Hirluin . With all the Outlands boosters he can have four , and seven . And all the Outlands cards are boosting each other at the same time!
Hirluin is OP in an outlands deck, which if you have The Stewards Fear you can make one. With Outlands cards, the Steward has nothing to fear!
