I don't have that deck, but I can look into it for next year. We'll see what comes out this year as well.

Little Sheepherder
Creature - Human Citizen
When this creature enters, each opponent creates a white 0/1 Sheep token.
At the beginning of each opponents end step, if you did not attack them that turn, gain control of a token creature they control. If you cannot, exile this creature then return it to the battlefield under your control.
0/1
Bringing their tails behind them

Again!

Line Builder
Artifact Creature - Assembly-Worker
Artifact Creatures you control cost less for each Artifact Creature you have cast this turn.
3/2
"One more for the line, and maybe we'll make quota...!"

Another Assembly-Worker!

Jawa Scavenger
Creature - Alien Artificer
Desertwalk
, , Sacrifice this creature: Return target artifact from your graveyard to your hand.
1/1

Let's get out of Star Wars and back to Magic! Make a Viashino!

Celestial Court
Enchantment
When this card enters, you become the Monarch.
Creatures lose Vigilance and cannot gain Vigilance.
Whenever a creature, artifact, or non-basic Land of a player who is not the Monarch is tapped or sacrificed, its controller deals 1 damage to any permanent they control unless they take 1 damage.

I think this may be under-costed. A repeat of the challenge please, see if someone can come up with something better or different.

legendofa URZADAMMIT, I'm so used to being Toughness Matters, now I have to think about the deck and if I want super-high toughness+trample, like Groundbreaker

Darksteel Stallion
Artifact Creature - Construct Horse Mount
Indestructible
Saddle 2
When this creature attacks, each creature that has Saddled it this turn gains Indestructible.
3/2

Another Horse!

Fallen From The Branches
Kindred Instant - Treefolk
Until the end of the turn, whenever a Treefolk enters the graveyard, exile it instead. If you do, create X 1/1 Green Saproling tokens where X is the mana value of that card.

Right, so while it doesn't count itself, it can count a copy if you cast two on the same turn, and multiple copies do stack. And milling counts.

Different Kindred card that isn't a permanent, please.
