How to easily get speed set mods?

You can't only rely on store mods. You have to farm them from mod challenges. Forget about upgrading for a bit until you manage to suit all your arena toons with mods. Then upgrade them and cross your fingers for additional speed secondary bumps.

3* the Tier 3 challenge and then farm, farm, farm. Sell the mods you don't want. Rinse'n'repeat.

Be glad that you can use any squad you want now.

It’s all RNG. Top players usually are whales that spend a ton of money to get a ton of mods to offset the RNG process by sheer volume of mods. The Mod shop helps too, if you have the credits. That’s where I got most of mine.

I have about 70 toons fully modded, and modded well enough to do very well for my f2p status. I haven’t farmed mods from challenges in a year. Got all mine from events and the store. The mod challenges ridiculously RNG dependent and the store/events seem to give better options than luck.

From where you are right now, I would say the fastest way to get them would be to concentrate on a phoenix team and use them to get through tier 8 of mod nodes, then do the speed challenges.

That's your pick then, I have all my toons fully modded and leveled. Most of my best mods are from farming dilligently for a long time...and many of them are speed sets which events never give. You can see the status at my profile.

The ops question was particularly about speed sets.
