It always blows my mind when some tourney opponents are virtually unbeatable and we have to battle dozens of times with them. It's not like the prize dragon is an Ultra Rare Champion type or anything, ya know?
I've just finished with Congo; it was looking like he was going to be another BK fiasco for me but I was pleasantly surprised when he went down after only 6 tries. Passion, Forbidden, Diamond, Fruition and Soccer all lost but my level 3 Forgefather came in and wiped Congo out with one super B and a little m to push him over the edge.
