: Draw cards equal to the greatest power among non-human creatures you control
Skip the $20+ cards (Thrumming Stone, Coat of Arms, Cover of Darkness) and the deck still hums: Commander: Karumonix, the Rat King (~$1) Engines: Pack Rat (~$3.30), Piper of the Swarm (~$3), Ogre Slumlord (~$0.45), a couple of Relentless Rats / Rat Colony (~$56 each cap the copies to stay on budget) Payoffs/utility: Crypt Rats (~$0.50), Nezumi Bone-Reader (~$0.40), Bontu the Glorified (~$3) as a sac outlet, Throne of the God-Pharaoh only if budget allows The rest: cheap black removal, Swamps, and a Sol Ring The whole list comes in well under $50, and it scales up gracefully add Marrow-Gnawer and Thrumming Stone later and the same shell jumps several power levels
For just five mana you get an anthem effect, giving your creatures +2/+2 as soon as you hit ten or more lands
It can also get in unblockable to trigger combat damage triggers and can even draw you cards with its untap trigger
4) Reverse the Polarity One of the few counterspells that handles all spells on the stack, this card is excellent against storm decks like Grapeshot
