Dear God, what is this degenerating into?
Silent Arbiter is an awful idea. Awful awful awful. You are Dragon Stompy. You are aggro by every definition of the word. You win games by swinging with large numbers of large creatures. You do not win games by running 1/5 creatures that keep you from swinging.
Faerie Stompy might get away with this guy because most of its attackers have flying and therefore it can afford to play a slower game due to evasion. Hell, you might find some deck that uses SA with Doran. But it does not belong in Dragon Stompy in any way whatsoever.
Silent Arbiter isn't red. It doesn't kill your opponent. And it doesn't fix your manabase. And it doesn't provide nearly enough disruption to warrant not doing any of these things. It's trash.
Everybody read this. Seriously. Hightower is 100% exactly right.
It's been mentioned about fifteen times in this thread. Razormane Masticore is eliminated from being played by the presence of Gathan Raiders and Rakdos Pit Dragon, who highly prefer you go into an attack step with no cards in hand. Razormane Masticore dies next turn if you ever do this. Razormane isn't as good as Gathan Raiders. No threat in the deck is as good as Gathan Raiders. Therefore if Gathan Raiders says Razormane can't be on the team, which it does, Razormane can't be on the team.
