[Domri recognizes Walter from their previous conversation and grins when Walter issues his challenge.]

Sure!

[He plants his feet shoulder-width apart and crosses his arms across his chest, trying to look the part of a beastmaster/chieftain standing at the head of his horde/war party.]

You can start it off, Fleshripper.

[Fleshripper happily bounces in place with a series of happy "Naw! Naw! Naw!"s. Domri looks back over to Walter. He'll treat this like a Gruul duel, which means...]

Challenger has the honor of first hit.

[Confidence is not something that Gruul lack. If they do, they won't admit it.

Considering that Domri has been busy training his team since he got here, that hit probably won't be as effective as Walter might hope.]
