I think Zanz has said something to the effect that he doesn't want to introduce Other-element creatures, though I could be wrong, maybe it was someone else. Either way, Other does not need Scavenger. That should remain the province of Vultures and lucky mutants... with this, not only can Death easily get 12 scavengers on the field, other elements can get Vulture's effect without luck or splashing Death quanta.
Don't take my first sentence as a cue that you should abandon this, I was just making you aware that the climate might not be favorable to adopting this into the game. Whatever you do, though, Scavenger should go.
