Here's my availability for the One Hit Wonder tournament (all times MDT = UTC-6):
Definitely: Weekdays 9:00 PM-12:00 AM, Weekdays 12:00 PM-1:00 PM
Kinda, don't 100% count on it: Weekdays 9:30 AM-12:00 PM, Weekdays 1:00 PM-6:30 PM
Even sketchier but might show up: Saturday afternoons
Rule of thumb: if I'm messaging you on Pokemon Showdown, I'm available right then and there.
