Randomness of data disks

I’ve collected 4 disks so far, and my luck up to this point has been bad (only 1 blue option and it wasn’t that great). That being said, I’m doing the same thing I did in normal: if the disk grants speed or turn meter gain, I pick it up. A few of my recent matches finished without the enemy getting a turn lol.

I guess I’m trying to say that you can make effective combos without purple.
