The 25-year-old Perera, who has been the pick of the bowlers for Kings XI Punjab team in the ongoing Champions League T20 tournament, said that having change-ups helped him leave the batsmen guessing.
"I am using lot of variations in my bowling technique. When someone hits a six, I like to bowl yorkers. I have lot of variations may be a slow ball and a leg cutter, I think I am quite successful with my variations," Perera added.
In both the games, Perera has impressed with his bowling, returning figures of 3-0-17-2 against Hurricanes, in which he also contributed with the bat, and 3-0-15-2 bowling figures in the game against the Tridents.
Among the upcoming games, KXIP now faces Northern Districts and Cape Cobras at Mohali on Friday and Sunday.
Perera admits that T20 is a batsman dominated game and a bowler has to put in extra efforts if he has to come out on top.
