This is my irl Tearlaments Lightsworn and I love it, about the deck it's very solid, and have some solid end board if your luck doesn't betray you as
Tearlaments Kaleido-Hearth and Rulkallos, Grapha, Masquerade, Number 38, Minerva and other.
I like the infinite possibilities you can play those archetypes so you may add or remove things like the shaddoll or despia and add something like Punishment Dragon, endless variants.
So as for combo line, there is none because it all up to what you mill, fortunately there are many ways to mill from the lightsworn spells like solar recharge and charge of the light brigade, to both Minervas, Raiden, Foolish Burial for Tearlaments every mill 3 cards.
My gameplay:
Plan A: is to somehow get to two level 4 monsters with wiese or tearlaments even on the field make Minerva Syncro, Summon two lightsworns make the Minerva xyz, mill with the second effect of Syncro Minerva then mill with Minerva xyz and have in your GY despa, king of the swamp, shaddoll and most importantly tearlaments to fusion into something.
Plan B: instead of Minerva Synchro go to Visas Amritara search the fieldspell and do tearlaments fussions or go into Psy-Frame and with two level 8 into Number 32 Hope Harbinger.
In best case scenario you will have something between plan A and B and in worst your opponent will play Dimensional Shifter or Abyss Dweller or something to lock you.
I am open for suggestions and opinion on this decklist and strategy, I probably miss on something but you will figure it out. (Grapha is best for first fusion because of his effect overwriting)
