Why Lethal Tempo

Lethal Tempo's bonus attack Speed synergizes well will Varus' passive as well as auto-attakc heavy playstyle.+

Why Triumph

Taking Triumph lets you fight to the death and hold your group for the kill, coming out the other side with massive health to keep fighting. If you have a reliable healing support (Soraka/Nami), Overheal can be a great alternative to for getting topped-off and entering small trades with the health advantage.
