This deck focuses on shrinking creatures (making them losing toughness), and having creatures get bigger when other creatures die.
• Shrink creatures (either -1/-1 counters, or -X/-X until end of turn effects)
• Creatures that get bigger (+1/+1 counters) when other creatures die
• Give out tokens
• Animate lands / artifacts (so they get shrunk and die too)
Some of my own creatures will due from the shrink effects.
