Mystery Players - Chemistry or Discount?

I am debating between getting the Chemistry (Orange) or Discount (Blue) variant for Ty Law and Tom Brady. Which should I get?

Given how quickly we’ve gone from discounted AP abilities to low-AP passive X-Factors, the chemistry Mystery Players are the only ones I’ve had an interest in. And of course the market for the broken Marcus Allen has shot way up.

Really, what answers your question best is ‘Which player will add more value to my lineup?’ If two additional chemistry buckets won’t substantially improve several starters, you go for the item that would be a starter in its own right.

The green Marcus Allen with 4 AP Unstoppable Angry Runs is, by far, the best of all of these players.  I'm so happy I picked him up.  I also have the green Von Miller with 4 AP Unstoppable Dual Threat, 2 AP Unstoppable Avalanche, and 0 AP Unstoppable Fearmonger.  Not sure which I'll use, but should be useful.

I have the green Marcus Allen and was switching between angry runs and wrecking ball….when I went back to Angry Runs….it was GONE!  Doesn’t anyone know if EA removed it? ??
