Speaking on The Block Unlocked podcast this week, Blaze revealed that the young couple have what it takes to win.
"Josh and Elyse are the front runners without a doubt," she said. "Sometimes people come out really fast and hard and put all their big moves at the beginning, but Josh and Elyse have really settled into their style over time."
Blaze also revealed that married contestants Jason and Sarah, who have experienced a very bumpy journey on the show, are the unexpected couple who could win.
"Interestingly enough though, Sarah and Jason could be the dark horse."
This week the couple were slammed by foremen Dan and Keith for the amount of defects in their house.
"The majority of the house needs to be redone," Keith said.
