Oz is one of the biggest powerhouses in WFA history and time and time again he has proven that. In 2004 Oz was out to prove himself to everyone in WFA. After failing to be a Canadian and a minister, he battled against Impact in a series of hardcore matches, which put Oz on the map as a hardcore contender.

In 2005, Oz challenged Impact once again and their ongoing feud continued for its second year. At Wrestlefest III, they competed in their third match up to determine who was truly the most hardcore. After a relentless attack from Oz, Impact was injured and this put Oz back on top of the mountain.

He returned in 2006 to go after the new Interborough championship but decided to align himself with his long time friend and partner, Slick Rick, in showing that they were still a force to be reckoned with. At Wrestlefest IV, Oz competed in a triple threat match for the number one contender spot for the WFA Championship and although he was unable to win the match, Oz proved that he could stand toe to toe with anyone and everyone in WFA.
