Equipped creature gets +1/+1 and has "{W}, {T}, Sacrifice Citizen's Crowbar: Destroy target artifact or enchantment." Equip {2} ({2}: Attach to target creature you control. Equip only as a sorcery.)

Toxic 1 (Players dealt combat damage by this creature also get a poison counter.) {T}, Pay 2 life: Add one mana of any color.

When Norn's Inquisitor enters the battlefield, incubate 2. (Create an Incubator token with two +1/+1 counters on it and "{2}: Transform this artifact." It transforms into a 0/0 Phyrexian artifact creature.) Whenever a permanent you control transforms into a Phyrexian, put a +1/+1 counter on it.

({W/P} can be paid with either {W} or 2 life.)
