The Wildcats' Australian prop Justin Poore was last week named in the 27-strong Exiles squad for the June 14 game against England but Agar believes he ought to have been joined by at least one of his club-mates.
"Some might use it as a focus," Agar said. "Our overseas players have been remarkable for us from this time last year and Poorey has come into the mix this year and added an awful lot to the squad.
"Timmy Smith's form over a long period of time has been very, very good. I think everybody acknowledges the influence he has on us and the creativity and smartness he posseses.
"Paul Aiton and Dean Collis have been in good form for us all year. Dean is a class act, a very good attacking player who has backed that up with some tough defence this year, while Paul Aiton is a true warrior.
"His form at the moment is through the roof. I think, pound for pound, he will give us as good a value as any player in the competition. If you are looking at week in, week out consistency, toughness and value for money, he'll take a lot of beating as a signing, particularly for a club like us."
Collis, now in his second season in Super League, was disappointed to miss out on initial selection for Brian McClennan's overseas squad but more disappointed for two of his team-mates.
"Paul and Timmy are playing really well," he said. "I was pretty confident Justin would get named because he's been playing pretty well and has brought a lot to our team.
"But I think Paul is one of the best players in the competition at the moment.
"Personally, it does give you a bit of motivation to try and prove people wrong."
