Collingwood are closing in on deals to secure Adam Treloar, Jeremy Howe and James Aish through a series of intertwined trades after the Brisbane Lions mellowed on their stance that they would not trade Aish.

Aish toured the Magpies' facilities on the Yarra on Friday as the Magpies entered negotiations with the Lions and Carlton over a three-way trade involving Tom Bell moving to the Lions and Collingwood trading a second-round pick to the Blues.

Collingwood and Melbourne were also locked in negotiations over what could become a multi-club deal for Howe to move to Collingwood, Jimmy Toumpas to move to Port Adelaide, Paul Seedsman to Adelaide and Ben Kennedy to the Demons.

A complicated exchange of second- and third-round draft picks is also involved in the mega deal.
