Irish challengers Schindlers Hunt and Mansony are among 10 rivals to reigning Queen Mother Champion Chase title-holder Voy Por Ustedes in Wednesday's two-mile showpiece at Cheltenham.
Alan King's charge was outpointed by Master Minded at Newbury last time and will again lock horns with the Paul Nicholls-trained youngster in the Seasons Holidays-sponsored test.
Nicholls will also run Tingle Creek hero Twist Magic, while David Pipe has entered Victor Chandler Chase winner Tamarinbleu.
John Murphy's Newmill won the Champion Chase two years ago and will return for another crack after finishing fourth 12 months ago.
Azulejo, Contraband, Fair Along and Lennon complete the 11-strong line-up.
Irish duo Fiveforthree and Forpadydeplasterer will not contend the Anglo Irish Bank Supreme Novices' Hurdle in the festival curtain-raiser.
Khyber Kim and Sentry Duty spearhead a four-strong Nicky Henderson raid and the well-fancied pair will be joined by stablemates Zebra Crossing and Binocular.
Like Captain Cee Bee, the latter is owned by JP McManus and is one of two four-year-olds in the race as Kahlil Burke's Lemon Silk also takes on his elders.
Other key names declared in the Supreme include last year's Champion Bumper hero Cork All Star, Deep Purple, Muirhead, Pigeon Island and Rippling Ring.
Saturday's Imperial Cup winner Ashkazar will instead tackle the Fred Winter later on the card.
