The hardest matchup for Old Passive teams are against Sacrifice-Barrier teams. One way of combating this is by perfectly timing Invincible and following up with a good combo to win.
This is the finals match between #2 seed Aemoguy and #1 seed Maiii in the recently concluded Rainbow Specials Tournament. The winner of the tournament gets an Emberdrake!!!
During PvP League, there is a glitch that sometimes occurs with sacrifice teams where the active move goes off twice in a row. This glitch is especially beneficial for people with 2 sacrifice mobs on their team.
Watch Chanco21's water team vs. a Leaf team.
