Everything in the Timey-Wimey Commander deck: all 100 cards with current prices, what the deck is worth against the sealed price, the 50 new cards, and whether it is worth buying.
Allons-y! — Whenever you attack, exile cards from the top of your library until you exile a nonland card. Put three time counters on it. If it doesn't have suspend, it gains suspend. Timey-Wimey — {7}: Time travel three times. Activate only as a sorcery. (For each suspended card you own and each permanent you control with a time counter on it, you may add or remove a time counter. Then do it two more times.)
I have to imagine this deck’s a bit of a headache for anyone new to Magic or players who just want to attack with creatures instead of fiddling with time counters and suspend cards. Personally, it seems awesome, and I bet most enfranchised players will be delighted to play with such a unique theme, backed up by powerful (though complicated) cards. The value is phenomenal, the theme is fresh and exciting, and the cards are strong. Not much to dislike, though I’ll give it a strike for being hostile towards newbies.
We’ve also got a sweet upgrade guide for this one!
Timey-Wimey's all about—you guessed it—time travel! It’s a Jeskai EDH deck that combines “time counter” mechanics like suspend and vanishing with the new time travel mechanic, which lets you either add or remove time counters from permanents or suspended cards you control. That’s already on the complex side for a Commander precon, but add a dash of phasing, some legendary -matters subthemes, and… what’s that? Soulbond and horsemanship? Yeah, they’re not playing around with these decks.
Rose Tyler and The Tenth Doctor partner up as the commanders. The Tenth Doctor freerolls cards into exile with suspend, and Rose Tyler beats down harder for every time counter you have represented somewhere. The cards are complex, but the gameplan’s simple: Get as many time counters as you can on your cards, keep your vanishing cards in play longer, and use the suspend effects to cast big spells for a small upfront mana investment.
As the name suggests, this deck takes time to do its thing, and it has a lot of moving pieces, but the individual power level of the cards is quite high, so it seems fun if you can get over the learning curve with all the new cards.
