Deal with the Problem

This deck tries to contain/control decks that "go off" (go infinite, do a huge Genesis Wave, etc.).
Instants that destroy, bounce, tuck, or exile
This deck uses a Nephilim (which is legal in my play group); I use this guy mostly for the colors, and Kynaios doesn't seem to help at all with this concept.
