Having initially dead-heated at the Welsh track last month, the nine-year-old was placed second after the stewards found he had interfered with Pinch Of Ginger on the run to the line.
Following a further look at the race, Oneida Tribe was actually judged to have crossed the line in first, but the result remained unaltered due to the original decision of the stewards.
Oneida Tribe left those memories firmly behind when opening his account under Rules in the Call Starsports On 0800 521321 Novices' Handicap Chase.
Dickin said: "It has been a long-term plan, this race. He won it in the manner I thought he might. The two I was most concerned about had recently run in heavy ground and they had to be tough characters to beat mine today.
"The Devon National (is an option), I'm not sure he would get in the weights and it might come a bit quick (February 23). I would quite like to run him in a long-distance race.
"There is one later in March over three miles and five furlongs at Warwick. I am sure we will have some fun with him."
Minella Voucher (4-1) survived a mistake at the last before taking the Sky Bet Britain's Most Popular Online Bookmaker Handicap Hurdle by a neck.
Richard Wiltshire, who runs Blue Blood Syndications, said of the Alex Dunn-trained winner: "He has been showing a lot at home but it has not come out on track. It is a relief to a certain extent.
"He runs in the blue and white silks which are the colours of Bristol Rovers and they won last night with a wonder goal and he has won today, so I am very happy."
Know The Score created a big impression on his debut for David Pipe when paying back a small slice of the £380,000 connections paid for him with an impressive 13-length victory in the concluding bumper.
Jockey Tom Scudamore said of the 1-2 winner: "He is a lovely horse and he has been working nicely at home. He is a gorgeous individual and it was a good performance.
"That was a great way for him to start and hopefully that is the beginning of bigger and better things."
Daryl Jacob moved to within one winner of reaching half a century for the season when steering the Ben Pauling-trained Delire D'Estruval (11-8) to glory by nine lengths in the Follow Us On Twitter Novices' Hurdle.
Jacob said: "We knew he would stay as we had him entered over three miles at Exeter on Sunday. We just thought with this ground we would come back to two miles as it is a bit easier."

PERFORMANCE OF THE DAY
Know The Score may have cost a small fortune, but he looked a potential star when winning what could be a useful bumper.
QUOTE OF THE DAY
Robin Dickin may now have his way with Oneida Tribe after taking the advice of Adrian Heskin this time.
He said: "The jockey suggested that I run him off top weight in a lower grade race because he is such a big horse. Now I want to have my way and run him off 10st against some good ones!"
