At a rally in PM Modi's hometown Vadnagar, Mr Gandhi claimed the Prime Minister was frequently changing the planks on which the BJP wanted to contest the Gujarat polls.
Rahul Gandhi's comments came as the first phase of the Gujarat assembly election wrapped up, with a voter turnout of 68 per cent.
"A magician also tries to hide something. When he performs tricks, he tries to divert the (audience's) attention. Similarly, Narendra Modiji has in the last 10-15 days tried to divert your attention from actual issues," Mr Gandhi alleged.
"Finally, he got frustrated and yesterday he accepted defeat and said he will not talk about issues but about himself. The truth has caught up with Narendra Modiji," he added.
PM Modi, at an election rally yesterday, listed all the controversial remarks Congress leaders have made against him in the past.
Rahul Gandhi alleged that PM Modi, who began his campaigning with the issue of Narmada water, had to abandon that plank after getting "exposed".
"Modiji started saying he will contest the election on the issue of Narmada water. It came to notice that the river water did not reach villages and went to the Tata Nano factory," he claimed.
"After 2-3 days he said he will contest election on the issue of OBCs. Even that did not work. Thereafter, Modi declared he will contest on the basis of 22 years of development. It, too, did not bear fruit." he added.
"After that Modiji says, 'Mani Sankar Aiyar said a bad thing about me, so this will be my election issue,'" Mr Gandhi remarked. He was referring to the "neech" slur used by the suspended Congress leader.
Referring to a report, Mr Gandhi denounced the Modi government for spending "Rs 3,700 crore on advertisements".
"Our government will use that money for your health and education," the Congress leader said.
He claimed that earlier the PM talked about jobs, corruption, schools, colleges and hospitals but he had stopped doing it now. "Neither does he talk about jobs nor about depositing Rs 15 lakh in your bank accounts".
The Congress spent 3-4 months in the run-up to the polls to prepare a manifesto after consulting various stakeholders such as "anganwadi women, Patidars, Dalits, famers, labourers, engineers, doctors", he said.
"In our speeches, we do not talk about ourselves but only about two things -- what the BJP did in 22 years and what the Congress will do in the coming five years," he said.
Rahul Gandhi also questioned PM Modi's "silence" on the issue of corruption, especially the graft allegation against BJP president Amit Shah's son Jay Shah.
"Modiji cannot escape Rafale or Jay Shah issues, whatever he may say (at election rallies). Even if he does not talk about corruption in his 200 speeches, the PM cannot escape this. Gujarat has decided that the next government will not be of industrialists, but of the poor, farmers, labourers and small businessmen," he said at a rally at Patan.
Mr Gandhi said during campaigning he will focus on 22 years of BJP rule in the state during which the ruling party "worked for five-ten industrialists" and "snatched land from farmers to hand over to Tata Nano".
"The Congress allocated Rs 35,000 crore to MNREGA, while the BJP government gave Rs 33,000 crore to the Tata Nano factory. Water from the Narmada went to that factory. The factory gets electricity for 24 hours when you get it only at night," the Congress vice president alleged.
Land from villages in Mundra was given to (Gautam) Adani at "Rs 1 per metre" rate, which the latter sold back to the government for "Rs 3,000 per metre", he alleged.
"Last year, the NDA government waived Rs 1.30 lakh crore of loans of 10 richest people. Farmers also ask for loan waiver, and (Union Finance Minister) Arun Jaitley and the prime minister say it is not their policy," Mr Gandhi said.
He promised a complete loan waiver to farmers in the state under a Congress rule.
"I promise that the Congress will get you the right price (for farm produce) and will also let you know in advance how much you are going to get," he said.
A Congress government will also spend money to improve health care facilities and education in the state, he assured.
Attacking the government on demonetisation and the Goods and Services Tax, he alleged that the winter session of Parliament was delayed because the PM did not want to answer questions on these two issues.
