X2 or X3 Team Chem ?

Kinda new to the game and i'm trying to find wich promo give the player X2 or X3 to his team.

For now I saw the stocking players giving X3

The new team diamonds look like they are going to be X3.

I'm 100% missing early one, can anyone help plz ?

Team Captains also give a x2 boost if I remember correctly

Team Captains give x3

All Team Diamonds including the ones tomorrow give x3

And Stocking Stuffers gave x2
