Queen Mother Champion Chase hero Finian's Rainbow has been entered for a first start of the season in the Amlin 1965 Chase at Ascot on Saturday.
Nicky Henderson's nine-year-old gelding took the two-mile Cheltenham crown when holding Sizing Europe in a lengthy duel on the flat due to a bypassed fence and went on to deliver a fine performance in the Melling Chase at Aintree.
Henderson could also run reliable yardstick French Opera.
Finian's Rainbow could have a testing comeback, though, as Nick Williams has entered his impressive Aintree winner For Non Stop.
Philip Hobbs also gives a chance to former Arkle hero and King George third Captain Chris.
Paul Nicholls' Ghizao, fresh from a confidence-booster at Kempton, and Martin Keighley's stable star Champion Court add further spice along with prolific sorts from shrewd stables in Quincy Des Pictons and Pepite Rose.
Mad Max continues his new career with Neil Mulholland, while Easter Meteor and Kumbeshwar have been entered by Emma Lavelle and Alan King respectively.
