More prompts means more cards. Seven more, to be exact.
Thousand-Year Kin Tree WBG
Creature - Spirit Plant (Rare)
T: Add W, B or G. If this mana is spent to cast a creature spell, that creature endures 1 when it enters. (Put a +1/+1 counter on it or create a 1/1 white Spirit creature token.)
You may cast creature spells from your graveyard by removing a number of +1/+1 counters from creatures you control equal to that spell’s mana value in addition to their other costs. Creatures cast this way enter with a finality counter.
0/5
[Abzan Watermark]
It's a kin tree that's lived a thousand years. Such endurance is the Abzan's speciality. It's extra impressive since it avoided being destroyed by Dromoka during her crusade to annihilate the Abzan's culture because she found it personally distasteful. The reanimation ability is a little complicated, but I think it's understandable enough. The ancestors fight on!
Orzhova Tux WB
Artifact - Equipment (Uncommon)
Equipped creature gets +1/+1 and has lifelink.
Extort (Whenever you cast a spell, you may pay W/B. If you do, each opponent loses 1 life and you gain that much life.)
Equip—Pay 4 life
In the Orzhov, you can’t afford to look any less than your best.
An equipment card to make sure your creatures dress their best. Putting it on is a little... hazardous, but there's a way to claw back what you paid. Kaya fans are surely disappointed that she can't wear this fashionable piece. Unfortunately, such a thing is too cool and powerful to occur.
Midnight Masquerade 4BB
Sorcery (Rare)
Exile all cards from your graveyard and separate them into two face-down piles. An opponent chooses one of those piles. Cloak each card in that pile, and put the other into your graveyard. (To cloak a card, put it onto the battlefield face down as a 2/2 creature with ward 2. Turn it face up any time for its mana cost if it’s a creature card.)
It's been a while since I've made a sorcery for a prompt. This one is a weird mass-reanimation that makes a mystery of everything. Well, almost everything. Your opponents get to know which cards were cloaked by this, and they'll know what's hidden from the pile sent back to the grave. But the exact identity of the newly cloaked cards will remain a mystery.
Moxite Cell 0
Artifact (Uncommon)
T: Add one many of any color. Spend this mana only to cast spells for their warp cost or to cast warped spells from exile.
“Where I come from, this would be worth more than a kingdom. Here, you buy it in bulk to burn.”
— Tezzeret
It's a mox! The connection to the prompt is that it's moxite, the fuel that makes spacecraft able to warp around the weft in the Edge. As always, Tezzeret is amazed at just how weird the Edge is from his perspective.
Seedcore Titan 4GG
Creature - Phyrexian Giant (Rare)
Infect (This creature deals damage to creatures in the form of -1/-1 counters and to players in the form of poison counters.)
Whenever this creature enters or attacks, proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)
6/6
Phyrexian Watermark
It's a titan that lives in the Seedcore, the deepest part of New Phyrexia from which Realmbreaker bloomed. It does the titan thing of having an enters/attack ability. The order with the trigger and infect is a little awkward but once you're playing a six drop you should have already gotten at least one poison counter on your opponent.
Moonlight Revelation 1W
Sorcery (Rare)
Return target card that’s an artifact or enchantment from your graveyard to your hand.
Overload 3WW (You may cast this spell for its overload cost. If you do, change “target” in its text to “each.”)
On Innistrad, some secrets become clearer when night falls.
Yeah there's a "moon" and a "moonlight" prompt. The moon draws us back to Innistrad, its light revealing secrets. This being Innistrad, those secrets might be better left buried. Or you can overload the card, regrow a whole bunch of goodies and worry about such trivial matters like "hand size" later.
Dawnfire Phoenix 3R
Creature - Phoenix (Rare)
Flying, haste
When this creature dies, you may put it into your library third from the top.
Miracle—RR, Exile a card from your graveyard. (You may cast this card for its miracle cost when you draw it if it’s the first card you drew this turn.)
3/2
Probably the most detatched from the prompt so far. The idea is it's a phoenix that returns with the dawn, represented by it going into your deck then being recast with the miracle ability. Feels too slow to be a major issue in constructed but might help grind out a win in limited.
