There is no official Magic card called “Lead Pipe.” If you mean “Murder” (artifact destruction or creature removal in black), some equivalent black removal spells are:

• “Doom Blade” (Destroys target nonblack creature.)
• “Go for the Throat” (Destroys target nonartifact creature.)
• “Infernal Grasp” (Destroys any creature, you lose 2 life.)

All commit similar targeted creature removal, keeping to black cards.
