I get what each one does individually, but what I'm wondering is how it works across a team. Does each member have to use the consumable for it to work? Take this scenario for example: a team hits three losses, which should mean their Trials run is over, but one member of the team uses the consumable to get the loss forgiven. Does the whole team get to keep playing until they get another loss? Or are they done?

Also, do you have to use the consumables before the games start, or can you use them anytime during?

Your buffs from the consumables and your ticket are all your own. When you get three losses, you have to go get another ticket to keep playing regardless of the rest of your team.

I assume that the consumables only affect your personal score-card-thingy. Since you don't have to run it with the same people for the entire duration of the card.
