Wales bring back skipper Alun Wyn Jones alongside fellow forward heavyweights Ross Moriarty and Justin Tipuric for their final Rugby World Cup warm-up match in Dublin on Saturday.
Coach Warren Gatland has changed all 15 of his line-up that started last Saturday's 22-17 defeat to Ireland at the Principality Stadium.
Ospreys talisman Jones comes in for Bradley Davies in the second-row to win his 128th cap while Moriarty and Tipuric, who have been nursing hip and ankle knocks, get a run out before the Six Nations champions jet off to Japan.
Jones will pack with Jake Ball in the Welsh boilerhouse with Dragons youngster Aaron Wainwright joining Tipuric and Moriarty in the back-row.
Wyn Jones, Elliot Dee and Tomas Francis are the starting front-row for the trip to the Aviva Stadium.
Scrum-half Tomos Williams makes his first start for Wales this summer while No.10 Rhys Patchell, who sealed his place among Gatland's 31-strong World Cup squad with an impressive showing off the bench against Ireland last weekend, starts.
In a strong looking back line Hadleigh Parkes and Jonathan Davies partner up at centre with Josh Adams, George North and Leigh Halfpenny forming the back-three for Wales.
Wales will face a formidable looking Irish team with Joe Schmidt using the game as a World Cup dress rehearsal for key opening matches against Scotland and Japan.
The Irish are poised to name their side on Thursday afternoon with the likes of Johnny Sexton, Keith Earls, Rory Best, Conor Murray, Tadhg Furlong and Rob Kearney all expected to feature.
Wales: Leigh Halfpenny; George North, Jonathan Davies, Hadleigh Parkes, Josh Adams; Rhys Patchell, Tomos Williams; Wyn Jones, Elliot Dee, Tomas Francis; Jake Ball, Alun Wyn Jones; Aaron Wainwright, Justin Tipuric, Ross Moriarty.
Subs: Ken Owens, Nicky Smith, Dillon Lewis, Adam Beard, Josh Navidi, Gareth Davies, Dan Biggar, Liam Williams.
