Skin lines in TFT idea.
I was thnking of ways Riot could enhance TFT to ad new comps and reasons to play them.
It seems like a pretty simple idea, but Riot could add skin line based team comps to the game mode.
The comp would only be active if you had all champions in the comp on your team, but they could make it obvious that you have the skin line buff by desplaing all the characters in that skin.
Example ideas:
Star Guardians Ahri, Poppy, Lulu, Jinx, Miss Fortune all in their star guardians skins.
Project team. Vi, Leona, Ashe, Lucian, Pyke, Warwick
If tehy ever want to add Kai'sa to the game, they get KDA line Ahri, Kai'sa Eve, and Akali.
I think it would be pretty cool and allow some characters to have some special extra synergies that could see more possible team comps, plus how cool would ti be to finally get the last champion you needed for a TFT comp and you put them in and you have 4-5 champions all change skins to look awesome.
