Abramov to entice Seattle to take Engvall.

Gives them an RD who's decent which is pretty important considering they currently have 1 signed for next season who's currently on the teams roster. Also gives them a very capable C or LW who is under team control.

Unloads a G which solves their current expansion draft issue. Giving up Fischer is tough, but the RD is important and they need D so that they can meet the requirements for players exposed in the expansion draft.

Leafs get a young pretty good goalie who can either be a backup or challenge for starter minutes. They also get a capable RW on a reasonable contract.

Flyers get a good penalty killer and serviceable forward who's cost certain and can play anywhere in the lineup. They also get a decent draft pick.

They also move on from a guy who's struggled to stay healthy and give him a fresh start, while avoiding having to go through a contract negotiation.

Leafs get a decent third line C, but has struggled with injuries.

Leafs move on from a player who doesn't really provide a ton of value to them apart from on the PK where they could find someone else for probably cheaper to do the same thing.

Buffalo bring in a star to try to convince Jack Eichel to stay. If they have to move on from Eichel they're basically screwed, so adding a star like Marner would probably help them on that front.

They also move Reinhart who is most likely wanting out, avoiding that situation, and they don't have to worry about signing Jokiharju now or Olofsson next season. Add in getting two good young D and a pick and I can't see them turning down this package.

The Leafs get a better disperse of money but keep the high level of talent from losing Marner. They also switch a LD to a RD which they will likely need if Holl is dealt/selected in the expansion draft.

They do have to negotiate two contracts, which isn't ideal, but it gives the Leafs a fresh start and a real reset in the dressing room.
