How should I assemble a combo machine of infinite death, preferably using an intriguing card from Innistrad? Hmm... Mentor of the Meek gives me that feeling of sliding into lunacy, so I'll start with that. If I set up a way to have creatures with power 2 or less enter the battlefield over and over, I could draw lots of cards. But... what if those draws provided tokens themselves, automatically? Ridiculous notion, right? Nah.

...for this situation is Words of Wilding. By paying 1 Mana, I can skip a draw to make a 2/2 Bear. Mentor of the Meek triggers and demands 1 Mana for another draw. I smell the makings of an engine, but I'll need an altar of some sort. Ashnod steps in with her famed contribution to Johnnyness. Now I can sacrifice the Bear for 2 Mana in response to the Mentor's trigger, to pay for the draw and the subsequent Bearifying of the draw. A couple eons of this and my Lumberknot becomes beefy enough to swing for the win.

The deck's other cards provide synergy. Sakura-Tribe Elder finds a land, is Meek, and pumps up Lumberknot. Llanowar Augur provides early weenie defense and another trample outlet for its Knotty friend. The aforementioned Behemoth Sledge is one of a small assortment of weapons in the deck. Mortarpod is pretty darn solid and triggers Mentor of the Meek, as does Skinwing (which provides additional evasion for Lumberknot). Finding these Equipment is none other than... Steelshaper Apprentice? I wanted to avoid using the stupendously busted Stoneforge Mystic, and the Apprentice actually fits into this deck better, since it and the Mentor make for an unwieldy card draw machine. A singleton Congregation at Dawn can find combo pieces or other creatures I haven't yet mentioned.
