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."

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."

QUOTE OF THE DAY
