Molineaux was the 10-11 favourite for the Carling Novices' Hurdle, having run well in handicaps, and it was straightforward enough, despite a fine debut run in second by Le Musee.
Valhalla, however, was the 7-1 outsider of three in the Direct Group Chase but Tizzard's inmate put his experience to good use.
Tom Scudamore was on board both those winners but Harry Cobden was on the popular Grand Vision, who outstayed Kayf Adventure to win the Dick Hunt Handicap Chase at odds of 6-1.
Now nearly white, the 12-year-old looked beaten half a mile out but his bold jumping came to the fore in the straight.
A step up in trip enabled Jubilympics (5-1) to open her account over obstacles in the EBF Mares' "National Hunt" Novices' Hurdle.
Seamus Mullins' mare had shown useful form in bumpers but had failed to cut much ice in two previous runs over timber, despite staying on with promise at Fontwell last month.
That was over only an extended two-mile-one, though, and up to nearly two and three-quarter miles, she kept on strongly under Daniel Samson to win by a length.
"I'm not sure what she beat but the step up in trip certainly helped," said Mullins.
"She's nicely bred and she qualifies for a mark now so we'll see what the handicapper does. I'm sure we'd try and win with a penalty.
"The mares' final at Newbury at the end of March could be an option. I'm not sure she's any better than that but she doesn't need to be.
"The trip and track would suit her there so we'll see what happens."
The dream run of Bryony Frost continued with the odds-on success of Captain Cattistock (8-11 favourite) in the Fortress Home Insurance Handicap Hurdle for Paul Nicholls, who doubled up with the long odds-on Unioniste in the hunter chase.
