Warren Gatland has announced his British and Irish Lions team to play the Blues on Wednesday, and it's clear that he is saving his heavy artillery for the Crusaders three days later in Christchurch.
It is a juggling act which could blow up in Gatland's face should the Blues, who will include eight All Blacks in their starting line-up, make the most of their opportunities at Eden Park.
In looking ahead to what is going to be a titanic challenge on Saturday from the Crusaders, unbeaten after 14 Super Rugby matches this season, it appears clear that Irishman Conor Murray will start at halfback inside England No10 Owen Farrell.
Welsh outside backs Liam Williams and George North are almost certain starters at AMI Stadium, as is England prop Mako Vunipola, in what will be close to a test-strength line-up.
Gatland's immediate challenge is to subdue a Blues team determined to create history as the first Super Rugby team to beat the Lions.
