Defending champions Leinster have three representatives in the Dream Team - selected by a media panel made up of three Irish, three Welsh, two Scottish and one Italian rugby writers - all of them in the pack as Sean Cronin, Rhys Ruddock and Jordi Murphy are selected.
Leinster's arch rivals Munster contribute two players, firstly Casey Laulala, the former Blues ace who has been a star in midfield for the men in red all season long.
The outside centre is joined by clubmate and loosehead prop Dave Kilcoyne in the Dream Team while Ulster also have two players who make the side.
In the backline there will be few surprised to see Andrew Trimble get the nod on the left wing, the Ulsterman roaring back to form this year both for his region and for Ireland.
In the pack Johan Muller skippers the side from the second-row, the World Cup winner has been an inspiration for the Ravenhill outfit in his final season before hanging up his boots.
The Ospreys are now out of the running for the play-offs but they too are well represented in this year's Dream Team.
The Ospreys have three players in Alun Wyn Jones who packs down at lock, flying Canadian Jeff Hassler whose seven tries earn him a spot on the right wing and fly-half Dan Biggar who is the top points scorer in the league with 204 - no other player has broken the 200-point barrier.
Scarlets look to have secured sixth in the table and they too have three players in the side, Gareth Davies getting the nod at scrum-half after a blistering season that sees him top the league try-scoring charts with nine to his name.
Glasgow Warriors have the final player in the team as Alex Dunbar, who despite an injury-hit campaign has impressed, joins Laulala in midfield.
