One of today’s daily challenges is win two oddball matches…problem is oddball is not on my playlist anymore, for some strange reason anybody else having this issue??
Try Team Objective or Crimson DLC.
> As if Snipers wasn’t enough to get you excited for the upcoming week, we’re also proud to announce the addition of Team Objective, which will group together 4 vs. 4 Team Regicide, Oddball and King of the Hill (she’s back!). The biggest changes you’ll see to these game types are that Complex Oddball has been removed, and instant respawn has been disabled for both KoTH and Oddball.

Correct me if I’m wrong, but if you play grifball it also counts as oddball.
