Incorrect Tier [Solved]

I’m gold level mastery in Blue, but when I joined a Journey through History: The Long Cold Darkness I got placed in the silver tier. I have a friend who made it into gold tier with just white mastered. Is this supposed to be a white event or something?

It’s an all colors except one event, so that’s correct!

Maybe the color restriction for these pve events could be communicated more visibly?

This event is non-blue. If you check the info (the i i n a circle top right) you can see the rules that apply and what colors and cards are allowed.

Ah! Thanks, okay, that makes sense. I never noticed it was non-blue because all my blue pw are multicolor

It is relevant, it changes reward levels
