New Oath things from BFZ

[Saya]

Greenwarden of Murasa:This is kinda updated Eternal Witness who is played in Oath decks sometimes.Putting him from Oath,we gather combo parts via cards like Time Walk or Diabolic Intent.We know the creature Rune-Scarred Demon,which has the similar action and archives success.

Void Winnower:Strangely the almost all spells of MUD has even cost.Oath sideboards perhaps?

[fsecco]

I like how Winnower stops Storm gameplan by cutting them off Moxen, Tendrils, Wish, Desire, Bargain, etc, etc. Against shops I don't know. It's funny that it stops Duplicant and Metamorph, so maybe it's actually good. This also stops Bomberman combo and Abrupt Decay. It has its merits. It can be Plowshared, though, so it's a risky play.

Greenwarden seems bad, way worse than Rune-Scarred.

You could run Cabal Therapy in your combOath deck, which would nicely net two Regrowths.

It will take a lot of convincing to get me to play Void Winnower over Griselbrand. Certainly it's the most disruptive Oath target yet, and if he comes out when you're not too behind on the board you will have a hard time losing the game. The problem is that unlike Griselbrand or alternative targets like Sphinx of the Steel Wind, Blazing Archon, and Elesh Norn, he doesn't do much when you're behind on board (not uncommon against shops, dredge, and mentor) and need to stabilize. Griselbrand is such a strong target because he excels at both offense and defense.

I think hes a sideboard target more than anything. People keep pointing out that he dies to swords, but he basically ONLY dies to swords and chain of vapor, anything else relevant is typically even mana, unless people start playing Beast within.

There are some decks where this is specifically unraceable though, and it is non legendary so you can pack multiples in oath and just keep going, all the while there tokens cannot interact with you. Some shops variants and a great many storm combo decks just cannot win if this resolves, no other cards needed.

Being colorless is also a non trivial thing as compared to all the black mana you need for G-Brand.

[fsecco]

I just metioned Swords because yes, it's probably the out that's most played. Swords can be Missteped too, so nothing is black and white.

He's clearly, if anything, a sideboard card, but I feel it's an interesting card to at least test. Not being blocked by tokens is a big plus that I didn't see. Neither tokens nor Young Pyro nor flipped Delver can block it.

I can't really think of common situations where Void Winnower is better than Iona.

[Aaron Patten]

Iona does almost nothing against shops. 

I used to play Witness oath with therapies to make infinite time walk turns after the first oath activation so that Greenwarden play is interesting but witness is easier to cast.

How does one infinitely recur Time Walk if you don't mind me asking?

[vaughnbros]

Eternal Wit is actually a fairly decent card (if not for GG it would be amazing).  If this guy was actually double eternal wit that would probably be playable, but you need a sac outlet and to exile it to do so I'm not really seeing its viability. 

Winnower is slightly better versus tokens than Iona.  I think both are rather underwhelming compared to just actually winning the game though.

Oath this up, regrow either a tutor or the walk if its already in grave, take a timewalk turn. Oath up second one regrowing time walk, attack with first one for 5. Take another walk turn, oath up last of these dudes (regrowing walk), attack for 10 and replay walk. Untap and attack for lethal?

Same principle as Rune scarred demon, you could probably also just regrow Ywill to assemble key vault or a lethal tendrils.

Opponent chumps with Spirit Tokens, breaking chain?

A few things need to happen.  You need a critical mass of tutors to make sure you hit a time walk turn on the first oath activation.  Then you need cabal therapies to get the first few witnesses back in the yard so that they can be Gaea's Blessing'd back into your library after a few oath triggers.  Then you need a source of sacrificing witness repeatedly so that once you've run out of therapies, and your opponent has no hand, you can still sacrifice the witnesses.  For example, I played a combinations of skullclamp, and Nostalgic Dreams for a while so that at some point you could fetch the sac outlet and the walk in the same walk turn.  There is a small chance of whiffing but in hundreds of games I think it happened only twice.  This new witness would replace the need for nostalgic dreams in that you could fetch the sac outlet and the walk in the same turn but casting witness is a big part of what makes it so attractive to oath into.  The idea was to eliminate dead draws and it worked for me.  This was many years ago when the best way to deal with oath was to simply counter or destroy it.  Witness did great work against that so it was desirable.  There is also Life from the Loam and Phyrexian Tower as a sac outlet that doesn't require you to fetch it.  While you're taking these time walk turns your also playing land and drawing cards and digging just like any other turn so you have ample opportunity to find the other pieces to make it last indefinitely.  In a deck that had a lot of tutors it almost never failed.  With the big guy you could just get key then sac to get vault but that's three dead draws in your deck so it's a little less appealing to me.  Not saying I won't take a look at it though.
