Are Mutant Ninja Turtles still effective?

Not really. In asso yes, but in normal gameplay I believe it gives you a slight advantage, but not like a year or 2 ago where you could absolutely dominate even stronger % teams.
For me not worth the time to do upselling, farm greens on multiple accounts and all that. Training players and focus on white skills yes, especially for associations, but not more.
Investing in a higher % squad with semi-mutants is better than creating 1% mutants.

Also I believe that if upselling would be a gamebreaking thing Nordeus would have done something against it already, like they did with man of the match bonus in friendlies. I think they are aware of it and nerfed it in a way that it doesn't give you huge advantages.
