The problem I have with this deck is how hard it is to beat stuff like Sej Plunder. You get absolutely wrecked by large creatures, especially those with trample and fury, while you durdle and don't actually get anything going. There isn't enough healing/board clear to catch up if your small creatures don't trade or threaten well. And it runs little removal. Maybe that means Ruination is worth running in something like this. Player skill can only compensate so much. It feels like playing Swain Leviathan but without the midgame removal to get to your win con.
