Surprise!

And what about Maverni national summons ? All France is waiting for Maverni national summons. Very influent magazines like Cyberstratege may start a press campaign and organize protests at the Swedish ambassy. With the french elections to come, nationalists and warmongers are going to exploit such a casus belli. Some even say that the french menhir throwers army is already preparing for an invasion. You must save peace ! Give Maverni some national summons !

"Horde of Boars" would be suitable.

"A sounder of boars, wild [12+]"

So, 12 or more Wild Boards per summon? Sounds right. "Sounder of Boars"? Well, that's a bit strange, but hey, it's grammar.

P.S. "Sounder of boards" was even stranger. I hate typoes like that.
