Final Tally:

Mown: 3
Cato: 1
TPzombieW: 1

And Mown takes it! Reification of Elori shall be added to the spoiler.

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

I feel like I'm doing a lot of white lately. Never understood why this is the color I usually do best in.
Make a white uncommon that uses a set mechanic. (Relics, oblation, mastery, engrave.)

Remake the Wreckage
Instant (U)
If an artifact creature died this turn, put two 1/1 construct artifact creature tokens onto the battlefield under your control.
Engrave


Playing with engrave in this way would usually be something to hold for a second set, but we're only doing one. I want some "build-around" engrave cards.

Instant

Destroy target attacking or blocking creature.
Engrave

You know, I think these would be cooler if opponents couldn't tell what was being engraved.
But I guess that's not really possible.

Sunchaser Procession
Enchantment (U)
Oblation — Whenever a creature enters the battlefield under your control, you may sacrifice Sunchaser Procession. If you do, put three 1/1 white Cleric creature tokens onto the battlefield.
Any sunchaser can ascend to divinity, so each new inductee is met with fanfare befitting a god.

The word you're looking for is "other". Also, that card is pretty rad.

I think I was worried about "destroy all other creatures" referring to all creatures but the servant, including the new one.

Blizzard Peak Shieldmage
Creature - Human Wizard
When ~ enters the battlefield, put a Relic artifact token onto the battlefield.
Sacrifice an artifact: target creature gains protection from the card type of your choice until end of turn.
2/2

Collector of Antiquities
Creature—Human Artificer (U)
When ~ enters the battlefield, put three Relic artifact tokens onto the battlefield.
~ gets +1/+1 for each artifact you control.
0/1

Creature
Flying
Enchantment Bringer (When this enters the battlefield you may cast an enchantment with converted mana cost less than this without paying that card's mana cost)
3/2

The engrave ability wouldn't go off until this thing is already dead. I believe that a creature is still consider an attacker briefly after combat damage is dealt, but I'm not sure. In any case, most players won't be sure whether this can target the thing that killed it.

Dunemire Escort –
Creature – Human Soldier (U)
Creature bringer (When this card enters the battlefield, if you cast it from your hand, you may cast a creature card from your hand with converted mana cost less than that of this card without paying its mana cost.)
"The wet sands close to Maraka are even more dangerous than the desert itself."
2/2

(Underworld) Guide --
Creature - Human Cleric (U)

Mastery - At the beginning of your upkeep, if you control an artifact, another creature, and enchantment and a land, put a 1/1 white Spirit token with flying onto the battlefield.

1 / 2

==xx==

I remember someone using a term for the underworld a while back, but I can't locate it ATM. That's why Underworld is in ()

Caravan Chaplain
Creature - Human Cleric
Mastery - ~ has lifelink.
2/2
Traders in the Scorch would be fools to travel without the blessings of a cleric. Merchants in that dangerous region recruit the highest order of holy man they can afford.

Did we ever hammer out the specifics of how mastery works? Looking at Altimis' card it never counts itself (unless it's type gets changed). It occurs to me that we should probably discuss the specific wording.

Chance to Make Right -
Instant
Put a 2/2 white Spirit enchantment creature token with vigilance onto the battlefield for each creature you control that died this turn.
Engrave

Altimis is doing it wrong. I suggested he do it that way in the Land thread once because it made sense for lands, but it really doesn't make sense that way, because if some of your permanents have Mastery and some others don't because they don't count themselves, that could get really confusing.

I vote for Steinhauser.

Ace of Moxes

cato

Ace - Only triggering off of artifact creatures seems too narrow for the nonengrave use of this card. Artifacts or creatures would have been fine. Maybe if you told me it was to ensure the card got around to the player drafting deck X. As is, it's kind of clunky.
Storyteller - Doesn't work like you would expect.
TP - You totally designed a common didn't you?
Others - Yeah, sorry I don't have time to do this.

Altimis gets my vote
