Syndra with Tear of the Goddess
Okay, so courtesy of a Syndra guide made by a player by the name "DJ Chrispy" I decided to build
on Syndra... And honestly, I think it's a better item on her than Morellonomicon or Athene's are. It definitely at least felt rushing
into
added more damage than Morello's and Athene's would. And the mana sustain on Tear isn't bad either. Syndra has mana problems to be sure, but Tear solved them just as well as a chalice would overall. Of course tear doesn't have chalice's mana regen passive but the base mana sustained me for quite some time, maybe moreso.
The big tradeoff would be the CDR loss. 
don't have CDR like
do. But, the only big problem I found with the loss of CDR was setting up ults was a little trickier, and while CDR is nice, Syndra's a burst mage. She kills her target in one rotation or she doesn't. The only spell she can even hit twice would be her Q.
