"Wayne has had a wonderful year, and the mare is little bit older with a quirky profile running over fences 18 months ago, but the team seem particularly happy with her.
"They feel she is in a better place this year than she was last year."
Blake said the Sons And Lovers was over-priced at $23 and liked the draw, barrier three.
"We wanted a soft draw," Blake said.
"He wants to be covered up, relaxed, and stall three is perfect for him and Dylan Browne McMonagle rides him well.
"Trustyourinstinct, he's a horse with a lot of ability.
"He's a high achieving horse and we would have loved a lower draw as he's a horse that will be ridden with a bit of patience.
"But when you need a magic act, you need a magician and we think we have one in JMac, not just James McDonald, but also J P McManus, two JMacs."
The fifth of the O'Brien team is Kizlyar who finished 11th in the Moonee Valley Cup (2500m) at Flemington on October 24, and in hindsight possibly should not have started.
"We brought him for the Melbourne Cup, and it wasn't planned to run before," Blake said.
"We felt he was right on the cusp to get in, so we tried to run to win and guarantee it, but as it transpires, we should have sat on our hands.
"It would have been some sweat if we did, but he's in.
"He's a strong stayer, he's a forward goer, but a typical Aussie style race last time didn't play to his strengths.
"People will rule him out because of what we saw last week, but I would be expecting a different horse on Tuesday."
Blake said he would like to see a strongly run 3200m contest on Tuesday, as he believes that will play into all the Irish-trained stayer's strengths.
"Trustyourinstinct has a wicked turn of foot, James J Braddock has shown a wicked turn of foot over shorter trips," Blake said.
"Goodie Two Shoes is probably more of a grinder, Kizlyar more of a grinder and Sons And Lovers can quicken off a quick pace.
"I think it favours the internationals when there's pace in the race because the locals are so good when the gears drop and they rev up again.
"We find them very hard to beat doing that, so we would be delighted to see pace in the race whether it's us pushing it or someone else and we would love a true two-mile test and we feel as a bunch, that would suit our horses better."
