Matchup 1 - Light/Water vs Light/Gravity (...)
I think this is johann's only bad deck these Trials. He just had too little damage to beat through Miracles, and no way to deck the opponent out, which cost him the win.
Matchup 2 - Light/Gravity vs Light/Gravity (wow, how original deck choices!)
I think this is a fair win. 6! Gravity Pulls > 5 creatures. johann didn't have a weapon, so he couldn't damage Ryan until like 50 HP and then drop 3 momentum'd Dragons, so he had small chances of winning, given he had the smaller deck,
Matchup 3 - Light/Time vs Light/Gravity (no kidding)
Lucky win is lucky. However, johann might've been better of with an Eternity instead of the Nymph, but still he got killed by the draw.
