I personally think the name of the tournament should have been: Stalls, Stalls, and more Stalls
(Seriously, I thought this tournament was supposed to be about little creatures???)
The stalls was really dominant, I found strange, but ... as Root once said "That's how you win tournaments, buddy. You find what's OP in the tourney's goal, and you use it."
But if there were no stalls, would be dominant armagio or forest spirit series, for those who have red-nymph make good combination with guardian, remove stalls of the tournament would be very limited.
(many creatures were removed, weapons and shields also remove stall cards would be very poor).
Tournaments are a concept with themes, however are not always as they should.
