Tims (Pingers)

Lots of pingers. I avoid pingers that cost mana to use.
Numot is used as a generic U/R/W color general; this deck doesn't abuse Numot in any particular way.
This deck could be 5 color: Black would add two pingers (Blood Cultist and Rakdos Ickspitter); Green would add untap effects (Seedborn Muse, Vitalize, Mobilize, etc.)
