Rising Stars are second from rear on the log with 32 points and were dumped out from the 2012 Federation Cup campaign by El-Kanemi Warriors in the Round of 60.
Lobi occupy the fifth position on the log on 48 points and are in the last 16 of the Cup courtesy of 1-0 win against Niger Tornadoes in Bauchi.
Tyavkase, who admitted to SuperSport.com that their confidence level has been boosted by the latest victory, insisted that Rising will suffer another defeat on Wednesday.
"Our spirit is very high and we'll surely record a convincing win at Rising Stars.
"Rising Stars' position calls for mercy but they won't get none from us.
"We want the three points to consolidate on our position and push to the top.
"Of course, we've never hidden our intention to win the league shield this season," he said.
The former Enyimba player is upbeat the Makurdi-based side can make it a double this season.
"We're in the race both for the league and Cup titles.
"And it's possible we win both titles. Our main target is to make it to the continent next year, so we must take the chances to achieve our aim," he said.
