On a more serious note, some cards for you to consider:[High Alert]Enchantment; {1}{W}{U} Each creature you control assigns combat damage equal to its toughness rather than its power. Creatures you control can attack as though they didn't have defender. {2}{W}{U}: Untap target creature.--NOTE: better than the Chariot you already have, as it works for ALL creatures, and leverages the higher Toughness of Defender creatures for greater damage potential[Plumeveil]Creature - Elemental; {W/U}{W/U}{W/U} 4/4 Flash, Defender, Flying-- NOTE: counts as a multicolor spell, synergizing with "Hero of Precinct One"
If you want a couple other options for the deck, Delay, Stifle, and maybe Righteous Authority. Also Detention Sphere might fit instead of O-ring.
