Hey guys, two quick questions. I tried to Google but found nothing really helpful.

First during the last tournament I was queued for player tournament matches and a sprout came in and queued for tournament matches as well. I got the ding to join a match and could see their name on the following screen and hit accept then immediately was put back into queue with a message "<player> cannot play Triple Triad at this time."

This apparently confused the sprout too who continued to queue over and over again and we got the same result until they just gave up and played the NPC. Is there a check based on deck strength? bad ping? sprouts can't play player matches in tournaments?

Second what are the odds (open ended question I know) of getting a 5* from platinum packs? Are we talking like warrior of light from gold pack odds or something a bit less extreme? Past four tournaments I got 3 packs each and got two Ultimate Weapons and TEN Shiva cards lol.
