Solphim, Mayhem Dominus Solphim, Mayhem Dominus doubles non-combat damage dealt to opponents and permanents they control, and thats what we should focus on when building this commander
On the chopping block: Lokhust Heavy Destroyer, Lychguard, Shard of the Nightbringer, Tomb Blade, Triarch Stalker, Flayed One, Hexmark Destroyer, Plasmancer, Royal Warden, Night Scythe

Since Mirri, Weatherlight Duelist has first strike, you dont have to worry as much about attacking with it to benefit from its abilities
Its magic is typically associated with the classical elements of air and water
I would personally cut the Saheeli - you might not know this as a returning player but planeswalkers without any dedicated support aren't typically worth running in commander unless they have an immediate impact on the game (something like Ugin, the Spirit Dragon for example )
