In icon swaps 4 there's a 94+ Mid or ATT PIM Pack, which guarantees an attacker or midfielder prime icon moments player who's 94 OVR or higher, which reduces the L ratio massively.
Here are the players you can possibly get, sorted by Rating high to low, divided into three categories, big wins, wins, and losses
Who are all approximately 1M and upwards (Garrincha 950k on the PS Market)
Who are all-around 700k PS market
94 Van Basten
So basically, out of the 17 players you can get, 10 of them are big wins that would upgrade any team (or 90% at least), 4 of them are very good cards, and 3 of them are undesirable, which gives you a 13/17 or 10/17 (which gives you around 67.6 % chance of pulling something good (58 if players on list 2 don't upgrade your team, and 76 if they do), with pack weight and such I think at worst the ratio will be 50% of good pulls.
Prove me wrong before I put my Icon swaps tokens in it.
