Are Assassin and Ninjas Meta in Season 2?

In pre-season 2 for Teamfight Tactics, I remember Ninja and Assassins being stupid strong.
It was always a near sure-win always as long RNG wasn’t harsh towards you.
Fast forward in Season 2 now, are Assassin and Ninja still a viable option to build in Ranked Matches.
Since I don’t play League of Legends Team Fight Tactics competitively, I am still quite low ranked; Bronze Tier.
Let’s check out if they are still good choice to build or did they completely fall off.
