I'm havin' a vision about ya
One card I think is very promising is Linessa, Zephyr-Mage. Ignoring her Grandeur ability, she appears to be a less powerful version of Temporal Adept. However, if you possess other copies of the card, she can sweep up an opponent's board with an admirable efficiency. If you are able to draw/tutor multiples or recur cards, you can regularly push back your opponent's development by sending a handful of permanents floating back to where they came from every turn or so.
The fact that you can employ Grandeur at instant speed is appealing, and you can still use Linessa's other activated ability. All of the Grandeur cards seem to be full of potential. I'm very interested in them, including the white and black ones which have been discovered.
Another card which appears very cool and unique, and yet is somewhat low-key right now, is Arcanum Wings. Aura swap looks to be a very exciting ability. The ability to get out any Aura in your hand for a activation (turn three, at the soonest, barring acceleration) is not a weak ability. Especially if there another card with Aura swap, this looks like it could have a solid place in a deck using a lot of powerful or versatile Auras, perhaps alongside Simic Guildmage.
Spellweaver Volute has some obvious potential. You can only replay your instants at sorcery speed, which means that it's ineffective to recur counterspells, but for many instants, that's a perfectly acceptable drawback. You can even replay a Remand on your own sorcery to draw a card, in a pinch. What's nice is that you can reuse these instants for no additional mana cost aside the original investment. Playing sorcery cards as you normally would can hardly be viewed as a drawback. And one aspect of this card that I think is easy to miss, but very significant, is that it can enchant an instant card in any graveyard - not merely your own.
Blade of the Sixth Pride is comparable, I think, to a higher order Savannah Lions. It's power is one point higher than mana cost, and it's still a low cost aggro creature. That should probably be a card which will see play.
The quality of blue bounce and library manipulation in this set is enticing. I love both such effects, and there are numerous choices including the aforementioned Linessa, Venser, and all of the various scry cards to choose from. It looks like I'm going to have a lot of resources with which to build a new, enjoyable deck. Spin into Myth, despite its considerable mana cost, seems promising. That operates not only as solid blue instant speed creature removal, but a way to influence your opponent's draws simultaneously.
I definitely want copies of Magus the Future. Magus of the Moat is an exciting card to see print, though perhaps less powerful than Moat (and rightly so). Magus of the Moon is probably much better than it looks, as is Magus of the Vineyard. I'm very curious about what the black one will be.
And from the look of things, the lands in this set will be very potent and desirable. Already we've seen a trend of impressive dual lands and single color producing lands with other useful abilities. As important as land is, this spells fun to me.
In closing, I greatly appreciate what I'm seeing in the rumors and spoilers. I understand why others are apprehensive about this set, but I predict it should be fun and full of goodies. Here we come, future! And it appears to be a pleasing one.
