Theory craft Swain- The next Generation of swains build ;)

Hey guys so I've been playing swain for 2 years now and i feel that with the nerds to his w and even the nerds to ROA that are coming and the past nerds that swain has died out in a sense. So i have been theory crafting to try and find a build that can allow swain to excel and I've come to this build which allows for earlier power spikes and deals with the tank meta. Rylais- Liandry's- Frost queens- situational situational toplane- zzrot, spirit visage, sunfire situational mid- zhonyas- ludens- void staff of course in the midlane you can exchange rylai's for zhonyas if against assassins. This build is more for mana regen. I have learned to control when to toggle my ult on and off. What do you guys think? So far I've experimented with it and it has worked amazing for me. Btw on first back i get another dorans for more mana regen then go right into rylais or liandry's depending on opponent. You can also get zhonyas first when they have a lot of assassins on the other team. Also you can get frosting early for mana regen and then go into the other items, then when you can finish frost queens.
