The Lions have a terrible record against the Swans, with just a draw in 2007 to show from their past nine encounters.
Not since a two-point victory in round one of 2004 have the Lions taken four premiership points.
However Power believes a new-look game plan under first- year coach Michael Voss gives them the weapons to break the drought.
"We have to take them out a lot wider because they're very good in tight," he said.
"We have to get away from the stoppages and make them chase us.
'"They are a tough opponent. They concentrate very heavily on tough aggressive one-on-one footy and that's where we'll have to match them.
"They've cut our good players out while managing to free their own players up and that's how you win games of footy."
While Brett Kirk invariably gets a role on Brownlow medallist Simon Black, Power also believed Lions midielders Travis Johnstone and Daniel Rich may find themselves closely-watched targets.
He said it was up to the Lions to counter any close-checking tactics and counter attack in return.
While the new game plan has been about high possession and quicker ball movement, Power said their entry into the forward line needed addressing and would hopefully result in more goals.
Another plus for the Lions in their bid to end the Swans hoodoo is the absence of clever forward Michael O'Loughlin and the injury cloud hanging over Barry Hall.
"He's (Hall) a really god player and goal-kicker and you don't want blokes getting injured but I wouldn't be disappointed if he didn't play," Power said.
"Also with Mick O'Loughlin out, that's two good goal-kickers and a lot of strength from their forward line."
On a personal note the 219-gamer has been in red-hot form in the first two rounds.
Ball has had 68 possessions, 29 of them contested, to lead the competition in both categories, while 17 clearances has him second in the league in that category also.
With first-half deficits of 25 and 41 points respectively against West Coast and Carlton in the first two weeks, the Lions midfielder said his team needed to do a better job of listening to the coach.
"We've got to stop losing concentration for those 15-20 minute periods," Power said.
"We're probably making Vossy haemorrhage in the coach's box because we're not following his instructions.
"It's pretty simple, we just have to be better at listening to him and following his game plan.
"Momentum is the biggest thing in footy and the hardest thing to stop. But you've just got to get the ball and slow things down until you can turn things back in your favour."
