New Wales coach Mike Ruddock has told his players that he "expects the highest standards" after selecting a 33-man squad for next month's tour to Argentina and South Africa.
The tour party includes three uncapped players - Llanelli Scarlets' full-back Barry Davies and Newport Gwent Dragons' forwards Peter Sidoli and Jason Forster.
There is a recall for Leicester prop Darren Morris, who last played Test rugby more than two years ago, but skipper Colin Charvis, record Wales try-scorer Gareth Thomas and lock Gareth Llewellyn provide an experienced edge.
Llewellyn needs only more Wales appearance to break Neil Jenkins' Test record of 87 caps.
Capped additions to Wales' RBS 6 Nations squad this season include Morris, Neath-Swansea Ospreys' back Gavin Henson, Cardiff Blues' fly-half Nicky Robinson and Celtic Warriors' lock Deiniol Jones.
Several top players will miss the three-Test trip due to injuries though, with Stephen Jones, Iestyn Harris, Robin McBryde, Martyn Williams and Gareth Cooper among those sidelined.
"We have a few injury issues which has given the opportunity for a couple of players to come into the set-up," said Ruddock, who recently took over from New Zealander Steve Hansen as Wales supremo.
"It's a challenging tour, I will expect the highest standards, and everyone involved will have to compete for the jersey.
"I am sure there will be new faces in the starting line-up, providing the new players reach the standard we want. And the fact that we are able to bring new players through at the highest level will undoubtedly pay dividends in the future.
"We are always trying to build strength in depth and this is a chance for one or two players to rise out of the shadows of others."
Wales meet Argentina in Tucuman on June 12 and Buenos Aires seven days later, followed by a Pretoria appointment with the Springboks on June 26.
Before then, there is a warm-up game against the Barbarians at Bristol City's Ashton Gate ground on Wednesday week.
The tour squad will be captained by back-row forward Charvis as Ruddock faces his first major challenge in the coaching hot-seat.
