eggman attacks

This is a midrange upgraded bracket 3 Grixis list with a high average mana cost and a mid-game clock around turn seven. It builds an artifact-heavy board, taxes hands, and cheats large machines into play rather than racing from turn three. Expect steady value, discard pressure, and a few heavier cards that should be mentioned before the game. Power is real but not turbo; pods should plan for attrition and mid-game spikes.
