I think you need to re-read over the tournament rules. Here's why:
"Last but not least, there are going to be two brackets; a winners and a losers bracket. I feel bad for the people that lose the first round (like myself last the tourney), since they miss out on all the fun so soon. I feel like this tournament is perfect for having a winners losers bracket, because it gives players another chance to try again. The only twist is, you'll be assigned a different weather for the losers bracket. With that said, I will automatically assign everybody with two weathers, so they can prepare both teams before the first round starts."
It has been randomly decided your two weathers are Sand Stream and Snow Warning! Remember that you can only pick one weather for each bracket, meaning that you can only use Sand for the winners bracket and snow for the losers bracket and vice versa. Seeing as you really wanted Sand, I'd choose Sand for the winners bracket, If you lose, then you HAVE to use hail in the losers bracket. Get my drift?
