It doesn't cost as much as you would think for event cards. I get 500 gold for each event so I can buy the cheap daily ticket, and always end up with the alpha SR. I don't waste tickets looking for the silver (if i find it before the SR, I take it.). Getting the normal event card takes longer if I have to look in the normal event gatcha box. Since the event box does not reset from one event to the next unless you do it yourself, I tend to have the SR slayer for the current event, and the beta from previous gotcha boxes.
