Finally there's the fact that the new Extra Monster Zone limited the use of Pendulum Summons arround the Extra Deck considerably unless with the assistance of Link Monsters, so recycling Pendulum Monsters from there thanks to "Pot of Riches" will assure its return in the next turns
Theres even the enchantment called The Cloning of Shredder (one of those accidental Lorwyn Eclipsed promos that has since been officially revealed) that makes copies of a creature in your graveyard that becomes a mutant as well
Partner means you can opt for a couple of cards in the Command Zone, and its not just the turtles themselves, with April ONeil, Live on the Scene, and Splinter, the Mentor, available, too
Grim Affliction Dont get me wrong, the most important part of Grim Affliction is the proliferate ability
There seems to be some limits that the game hasnt crossed yet despite years and years of aggressive power creep
