Necroserpent, Presserpent and graveserpent are anti-SS that can stop 1-2 SS in a turn, and if your opponent plans to avoid SSing, Depthserpent Promote SSing to the opponent. Viruserpent and Splaserpent are hand destructions upon their destruction and being sent to the grave and due to their Level they can clog hand sometime. so it can be hit and miss thing
