Definitely a very strong team.

I'm very curious how the Frontier matches change over time. Right now, I'm already getting kind of bored by the new game mode, because I face the same 2-3 team variations in every battle and many battles are just decided randomly because the enemy has the exact same card as me and one just happens to attack first.
I guess this might change over time, though, when people get more cards and are able to level them up. It's probably still too early to give a final judgement of the new game mode and it's possibilities.
