For those that are wondering how many cards they would need to complete these objectives where you need to acquire these 92 cards to complete all of the objectives. EDIT: Someone else posted this before me only noticed after the page refreshed.
If you are someone who does it all though exchanging 85s
92OVR = 5x 89OVR
89OVR = 3x 87OVR
87OVR = 3x 85OVR
Not going to go further into it but to get 1x 92 you would need 45x 85 overall cards. and if you want to complete all objectives 45x4 is 180x 85 overall cards.
If you choose to acquire the two of the five 89s needed elsewhere because they are not specific to the event, you would need 27 85 overall cards to get the 3 event specific 89 overall cards so 27x4 is 108 85 overall cards still needed with the remaining 8 89 overall cards acquired elsewhere.
If you do both you will range between 108 - 180 85 overall cards needed to acquire the 4 92 overall cards and complete the objectives with them. Outrageous...
