digiman619 - Strong card. Especially the -3 ability, that one’s really powerful and versatile.
With how closely related the two minus abilities are, I don’t really see how the plus ability fits the design.
The -7 is reasonably strong. It needs setup for its first ability (which is unlikely to bring a whole lot to the table, as it should be dead by then, as it needs ~6 turns to set up for one ult copy), but its draw 7 ability can be strong enough in and of itself. Also about the ult: I find it odd that all exiled cards go back into your library, as it’s very rare that the exile zone is accessed outside of cards exiled by imprint. Though, it is an ult, so not like it’s cheap to do.

gluestick248 - Very specialised card. A card you can really only use as a sideboard card, as it needs the opponent to run black. Otherwise its swampwalk and -3/-3 abilities are useless to an active deterrent to playing it, as you might have to debuff or even kill one of your own black creatures. Its cost is also very expensive and means it has to go into a black deck, making it even harder to find a place in any deck. First thing I thought of when I looked at the card was Skinrender, and that it’s severely outclassed by it in general use.

Jartis - Interesting design based around already existing hand-amount-based designs, though I’m kind of afraid that it is a bit snowbally. It already thrives on card advantage, and the low amount of cards in an opponent’s hand means that they’re less likely to have an answer to your card. Added to that is that the answer cannot be a blocking creature, because shadow makes it unblockable to most creatures. Cool flavortext.

Flo00 - Nice build-around design. It gives much more added value to -X/-0 cards, especially if it’s in a commander deck. Blue is also the unblockable color so that checks out. Its cost is a bit heavy though with how much of a downside it also gives your creatures, as it will need plenty other cards on your field to actually do much of anything.

ameisenmeister - an odd card that needs very specific workarounds with land-fixing in a multicolor deck that I doubt will be worth it for the manacost it has.

Boogymanjunior - I like this card. Great condition, that makes it essentially an 8/5 if its blocked by one creature. Also nice that it can still be blocked by an opponent’s creature, but they only have one shot at hurting this creature. Would also work well with other -1/-1 counter engines.

gateways7 - This card is all about versatility, and it does so flavorfully. It contains the three colors well in its modes. The modes are fairly weak on their own, but because the card is about being versatile, it’s more logical that that’s the case. Its three colors, though fitting in what it can do, makes it a lot less versatile in which decks can run it though.
Textwise, it is “at end of turn”, there are no “the”’s used anywhere in the syntax for those sentences in magic.

2wb - A strange card, that I had to do a once over on to totally get. It essentially allows you to have all creatures be unblockable for one round (a turn for all) starting with yourself. The -2/-0 is a flavorful addition, but it doesn’t mesh quite well with the second ability of having unblockables. It essentially nerfs itself. Also, I don’t really get where the black mana comes from, as these two effects are really mostly blue and a bit white.

Anywaysawinner:
The winner is Boogymanjunior with Deathveil Oppressor. Flo00 is the runner up. Thanks for playing!

{Spoiler}Nice flavour, fusing Zendikar's destruction with new hope and reflecting it with the abilities.
Abilities themselves are contradictory, requires playing a reasonable amount of Wastes in a deck to make it playable, enough to interfere too much with a color-heavy deck.
Small point, all Moxes have normally CMC zero.

{Spoiler}Body and ability mix doesn't seem common. It really looks like it should have flying.
Rather odd and weak: the flicker ability is only mainly used to protect it from getting destroyed by the smallest things after investing 7 mana for a mere 7/7

{Spoiler}Nice way to get an almost unblockable creature in red-green. Simple, but fun and mean. In need of a flavour text.

{Spoiler}Cool card with an interesting ability, especially vigilance and lifelink together giving the opportunity to attack, then use the ability on yourself,then gain life to miltigate a possible life loss. However, the ability is still too shaky for me, often too good or too weak.

{Spoiler}Solid fun card, especially the mechanical link between the effect and the basic land cycling. Might be a bit too strong considering Jaws of Stone which is not a bad card, but which needs way more effort/restriction while having no early game alternative.

{Spoiler}I like spicing Persist with an advantage after the first death, although Undying kinda already takes this place.
Nice Orzhov flavour, making her a flying spirit after dying. Other than flavour though, the ability has not much need to exist.
Activated ability needs to have the standard clause that cards reentering the graveyard this turn get exiled, otherwise too easy breakable.

{Spoiler}Very potent, rather too strong. Would be better reflecting the Helix by giving it lifelink, and in general to cut one or more other abilities and/or increasing CMC. Also, as it is now, there is no white in it.

{Spoiler}Nice card, flexible, powerful but balanced, synergistic. At first I thought this might be too strong just by thinking of paying 6x and possibly boosting +6/+6, but vigilance instead of trample miltigates that.

{And the winner is...}melono ! Followed by ameisenmeister , gateways7 and Lady Mapi
