This card seems extremely strong to me. 

The first thing I thought when I saw this cards was:  Does this card make a High Tide combo deck viable in Vintage.  If you think about it, it may be possible to play High Tides and Resets /// and then use Quicken to play Yawgmoth's Will after making a ton of Mana during your opponents turn Via the Tides and Resets.  It is also relevent that the Quicken actually cantrips, and that it is reusable under the Yawgmoth's Will, so it would be possible to cast Tendrils off the Will.  All of this would be during your opponents end step, and since the deck would look very close to Mono blue there is a very good chance that the mana base would be more stable than prexisting combo decks. 

We are still working on an initial list and haven't even begun to test this deck yet, but do any of you guys have thoughts or ideas regarding this style of deck.

The main problem I see is that you can't play moxes when you are comboing out, however the hightides and resets actually just make stupid amounts of Mana, so you don't actually need them to go off. 

It also doesn't seem terrible that with Quicken you could play a Draw seven at the end of your opponents turn and then untap and try to win.  Rather than play it on your mainphase and pass to your opponent who has a full grip.

Thoughts?
