I noticed the time left on the tokens matches the ending time of the current Round, and was wondering if that was the reason (unless the next Rounds give out Heroic tokens instead, like in some previous long events).
last simulator, the tokens had all of the buffed *** chars at once
They contain the rotating buffed heroes. The reason I think the tokens run out at the end of the event is because the 10 pack currently gives a guaranteed Psylocke.
It will be a different 3* buffed for the next run so the next tokens although the same, the 10 pack with include a guaranteed cover of the next max buffed 3* - be it Doom, BP or Thor.
OR DAREDEVIL
The 4 major buffed Characters I believe Are Psylocke, Black Panther, Doom and Lazy Thor.
Daredevil already has a minor buff and should stay that way for the whole event. 
yea but he’s still in the token ;(
There’s no running from Daredevil!
