Disclaimer, that objective is a coin commitment so only do it if you really care to knock out the dang objectives.
Today's CUT tweet mentioned "Star" players from Eggstravaganza. The LTD's and Champ players have three yellow stars on their card art. You need the 3 champs (don't need the LTD's but i would assume they would count instead of one of the champs) then the free Rabbit Evans and any 94 Eggstravaganza player (so a total of 5). Once you have the 5 in your lineup, complete ANY of the polar vortex challenges.
The easiest is the Alien section. First challenge about a Hail Mary. Just complete it 5 times in a row even with repeating it. You don't need to go back to the menu each time. Once you've done it 5 times, the objective completes (once for each time) and you'll get one of the egg containers.
Again, this is NOT worth it if you don't already have 3 champs because you'll have to buy them then sell back at a decent loss. This is really for completionists only at this point.

You may also need Coach Goose as your coach. I happened to have him as my coach already so if it doesn't track then add him as your coach as well.
credit to - saw his tweet on X. i used his info and laid out the steps a bit more clear
EDIT: It seems like you only need 5 Eggstravanga players. not necessarily all 3 champs (coach goose seems to count). Below someone mentioned having only 2 champs, coach goose, and two lower players and it tracked. Another user mentioned any five Eggstravaganza players including coach goose worked.
