Thanks to everyone for the comments including Matt, wiley, & Hrishi.
Story behind the deck:
Sometime in the late Spring, Rob Edwards challenged me to Top 8 with a maindeck Sen Triplets. I agreed to make the attempt but the Lancaster Invitational and NYSE were right around the corner so I said I would do it sometime afterwards. After the NYSE, I picked the August Bloomsburg for the time and place. It is my "professional" opinion (if such thing could be said to exist) that card is not suitable for competitive Vintage play but a challenge is a challenge. The card has an incredibly cool effect but because of its awkward CMC, vulnerability (5 CMC Human that dies to Ancient Grudge, seriously), and delay in effect, it's unreliable and compares very unfavorably to similarly costed cards like Magus of the Future, Tezzeret the Seeker, et. al.
Nevertheless, the venture was unforgettable because in round 1, I was paired against Rob himself and courtesy of an early Show and Tell that required tapping out on his part, Griselbrand and Sen Triplets went head to head. Hoping to limit my opportunities for conversion, he passed the turn without drawing. On my upkeep, the Triplets triggered with devastating effect. I had Mikokoro, Center of the Sea in play. I used it (being able to play your opponents' spells is one definite way to counter its symmetry). I cast Timetwister, taking Rob's Lotus and his Time Walk. He also had Yawgmoth's Will in hand, so I used to to replay my Timetwister, with full access again to both of our hands, which included more acceleration including Rob's Emerald. I drew my own Time Walk, played Auriok Salvagers and killed him with Pyrite Spellbomb the next turn. It took a bit longer to figure out how to finish the game because the match was an Oath mirror and many of the cards I was seeing in my own hand were useless copies of Oath of Druids. It was a bizarre and unprecedented game state whose irony (being seated across from the very person who challenged me to play the card) would have been too contrived had it taken place in fiction.
Later that day, I also learned that Sphinx of the Steel Wind is an awesome Tinker target against Dack Fayden/Delver Aggro.dec. The fun came to a screeching halt in the quarterfinals when Kohler landed (surprise, surprise) an early Jace in game 2. In game 1, I stopped his set up for Turn 2 Magus of the Future with Force of Will, but because Force of Will is such a terrible card, using it simply delayed the inevitable as it often tends to do. It's probably time to revert to the original and correct amount of Forces which is -zero-.
Thanks to Shawn for hosting another great time.
