Dermot Weld holds a strong hand in Wednesday's Group Three Irish Stallion Farms E.B.F. Blue Wind Stakes.
The Rosewell House trainer relies on three-year-old fillies Tarfasha, who is making her seasonal reappearance, and Tahaany, a winner already during this campaign, in the mile-and-a-quarter heat at Naas.
Tarfasha won her juvenile maiden in Galway last July before signing off in September with a third-placed finish to My Titania in a Curragh Group Three. Pat Smullen takes the mount on Hamdan Al Maktoum's filly.
Leigh Roche gets the nod to partner fellow Al Maktoum-owned runner Tahaany, who stepped up to this level last time out when fourth in the Athasi Stakes at the Curragh.
Euphrasia, who served up a 33-1 shock when making all in this race last year, is back to defend her crown but she has concede upwards of 3lb to the field.
Trainer Joseph Murphy said of the five-year-old: "I'm expecting a big run. It was yielding to soft last year when she won and hopefully it is the same.
"She's a filly who is very good on her day. I'm happy with her since Gowran Park (where she ran last month). Gary Carroll rides Cristal Fashion so we had to go hunting for a jockey so Wayne Lordan rides her."
Mizzava, the highest-rated filly in the race off a mark of 105, represents Mick Halford. The four-year-old was fifth in both the Irish 1,000 Guineas and the Coronation Stakes last year and she holds an entry in the Pretty Polly Stakes in the Curragh at the end of June.
Halford said: "I was happy with her in Gowran. She has come on a lot since then. This looks a good opportunity for her. I'm hoping she will progress as the season goes on. She settles in her races and I've no worries about her getting the trip."
Des McDonogh's Morga is an intriguing contender, having finished fifth in a Group Three at the Curragh in March before winning a maiden hurdle at Cork and then a novice hurdle at the Punchestown Festival.
McDonogh said: "She's in such good form that we have decided to run. There's nothing to run her in over hurdles now. She's in good heart and has come on from Punchestown. This is my first ever runner in a Group race. She's owned by Jim Bolger's wife and Kevin Manning is on board. It would be great to get some black type with her."
Champion trainer Aidan O'Brien runs Dazzling, who holds engagements in the Irish 1,000 Guineas and Irish Oaks and is likely to go off favourite. Cristal Fashion for Ger Lyons and Paul Deegan's Achnaha also line up.
Earlier on the card, O'Brien's War Envoy goes head to head with the Lyons-trained Cappella Sansevero in the Fishery Lane Race. Both impressed on their debuts, with War Envoy winning at Naas, while Lyons' runner scored at Dundalk.
