Magpies coach Nathan Buckley warned on Wednesday of the perils of taking the foot off the pedal in the final round after his team "never really recovered" from being smashed by Geelong the week before finals in 2011.
But Clarkson said the Hawks would be at full strength with the exception of Cyril Rioli and Matt Suckling, and expected a strong showing from his team.
"It's business as usual. It's a great chance for us to rehearse our game plan for this week's game," Clarkson said.
"We've got a great opponent in Collingwood who are fierce competitions and have been great opponents of ours for a good period of time.
"It's just rehearsal for us and I think we found a gentle reminder of that in the first half last week, not that we went into the game without a full-on approach but you know that anything below your very best is going to leave you short of good opposition.
"We rate Collingwood as a very good side, they've got a lot to play for and we've got to make sure we get ourselves right in time for finals footy.
"We think the best way to do that is continuity of your same group of players playing together and going into the finals with really good momentum and winning form."
Josh Gibson trained on Thursday after stubbing his toe against Geelong on Saturday night and Jack Gunston moved well despite landing awkwardly on his ankle last week.
Suckling didn't train and will miss this week with knee soreness but Clarkson said he was confident he'd be fit for the first final.
