This deck turns into a real powerhouse on turns 2-3 with a
swarm of creatures followed by beefier beats in the midgame.
It's worth noting the almost-broken interaction between
Ranger and the mana-producing elves. You can lead with first
turn Llanowar and then second turn tap the elf and two
lands, drop the Ranger, return a land and untap the elf for
another mana. It's quite easy to drop your hand.
Rancor, Bonesplitter, Wargear, and Genju offer reusable
power throughout the game. They also give you more options
for using mana in the mid-game.
Genju acts as a 4/4 haste creature. Ridgeback makes an
excellent target for Rancor and you get the enchantment back
after it dies.
Quirion Sentinel is an overlooked 2/1 for one essentially.
This, coupled with Bloodlust on Skarrgan, leaves you with 16
2/*'s with mana cost of one. Skarrgan can become very scarry
for an opponent when he has a Briar Shield, a Rancor, and a
Bonesplitter on him and can often finish the game.
The ability to win against a goldfish as early as turn
3 is quite good in peasant magic.
The deck also has Giant Growth as a combat trick or a
finisher. Most opponents will try and bolt a creature you
play Rancor on. Imagine their surprise on turn 2 when the
2/1 that was going to become a 4/1 now becomes a 7/4
trampler until the end of the turn and they've just lost a
burn spell.
