Trials Cycle / Monthly Event Cycle

I’ve found once the cycle for Monthly Event but cannot find it. I do believe Trials, and Monthly Event (Rare Epic Legendary) cycle.

I’d like to ideally find a google sheet that has the cycle of The Trials, and classes, possibly even heroes
that we face, but am happy with just the Name and two classes associated with it.

B) The Monthly Event.

I’ve participated in two, so I don’t really know the cycle. Same as above if someone could link me to a sheet that has the cycle, and possible more info. If I remember correctly there is a sheet with Rare, Epic, Legendary and the color/number of enemies.

TLDR. Thanks in advance, any help is appreciated.

These cover all of that:
