Steinhauser, despite strictly-bettering mulch.
Shazzeh as a close second.

Mown

I wanted to choose storyteller since i specifically suggested green-spine mastery would be a cool draft deck.....but story's card doesn't help.

Shazzeh

Final Tally:

Knifethrower: 3.5
Mown: 3
storyteller: 2
Steinhauser: 2
Shazzeh: 1

And Knifethrower takes it! Wanderlust Wendigo has been added to the spoiler.

Please pick a rarity and write a criterion for the next round.

Well-rounded common 2 drop; i.e. grizzly bear+ish

Polar Bear
Creature-Bear (c)
Hexproof
2/2

Swiftspear Shaman –
Creature – Viashino Shaman (C)
Whenever Swiftspear Shaman attacks, add one mana of any color to your mana pool.
[Instant watermark]
2/1

Loamblood Druid
Creature - Human Druid (C)
Oblation — Whenever a land enters the battlefield under your control, you may sacrifice Loamblood Druid. If you do, search your library for a basic land card and put it onto the battlefield tapped. Then shuffle your library.
"May the land not wither as I do."
2/2

I think Shazzeh just won this round ._.

Taiga's Whisper
Creature - Spirit
Forestwalk, Fleeting
1/1

With all due respect, Fakeartist, you're sticking Fleeting on random things to whose design Fleeting doesn't add anything. Give them ETB triggers of some kind and your cards would be amazing. Like if your common green gained you a life or two, and your mythic angel exiled a nonland permanent.

Augur of Ancient Arts --
Creature - Dryad (C)

Mastery - As long as you control an artifact, another creature, an enchantment, and a land, Augur of Ancient Arts gets +2/+2.

"If you listen carefully to the nature surrounding you, you willl hear legends of when Starstill moved."
-Einamorial, Dreamer of Marakas-
2 / 2

Glamerwalker
Enchantment Creature - Spirit
Enchantmentwalk
2/2

Celebrated Cartographer
Creature - Human Scout(c)
If a land would enter the battlefield tapped under your control, it enters untapped instead.
2/2

Probably not a common now that I look at it.

Dune Ants
Creature—Insect (C)
Dune Ants can block an additional creature.
Dune ants travel in pairs. Should one ant die, the other drags its carcass back to the colony so that nothing is wasted.
2/2

Seasoned Traveller -
Creature - Elf Druid
: Add or to your mana pool.
1/2

I'm not sure about putting 2 2/2 for at common in the same set, maybe mine should become a 2/1 if a bear wins this round.

Lost Cub
Creature -- Bear (C) [1/1]
, Sacrifice Lost Cub: Put a 3/3 green Bear creature token onto the battlefield.
The hunter hadn't been the only one to hear the cub's cries.

Yeah, I checked the set map before making this criteria, but it was out of date.
However, it is not uncommon for green to have three 2-drop creatures; a bearish beater, a defensive creature, and a techy creature. Depending on what wins, pushing stats around on something or other should alleviate the issue.

I love where you're going with this, but Bear tokens are always 2/2 and I think it could fit in with the set themes better if you tweaked it a bit.

Lost Cub –
Creature – Bear (C)
Oblation—Whenever a creature enters the battlefield under your control, you may sacrifice Lost Cub. If you do, put a 2/2 green Bear creature token onto the battlefield.
All it needed was a trainer to help it grow.
1/1
