It's interesting how much difference a single
sentence can make - and not just in Magic, but
that's rather beyond the scope of Card of the
Day. In the case of Day's Undoing, the clause
that ends the turn is the difference between the
literal world-breaking insanity of Timetwister
and being "only" a good card. You don't get to
cast anything you draw this turn. But think of
all your favorite spells to cast, and of all the
cards that you've ever lost the game to. They're
just as good on any turn you can afford them,
and though your opponent has seven new cards to
look at too, they could equally have been forced
to shuffle away the answers they were holding.
Today's card of the day is Day's Undoing which
is a three mana Blue sorcery that has each
player shuffle their hands and graveyards into
the library and draw seven new cards then your
turn ends. This is a strikingly similar
card to Timetwister with the potential to do
more on that turn removed, still leaving it as
an incredibly powerful card in the right
situation. Simply having mana available to
cast instants or cards with Flash on the next
turn is one of the ways to get around the
drawback and it will definitely be seeing
frequent play across formats.
In Limited this can help an opponent as much as
it helps you, but it can not be passed in
Booster for both value and potential in game.
Timed well this can set up the end of the game
even if the opponent gets the first main phase
to use cards, though countermagic should be
drafted to support it when possible. In
Sealed it is probably enough to force splashing
Blue by itself and the other color is best if
instants are in abundance.
Whew. when I first read it, instantly thought of
time twister and went a little mental. Then it
wore off. People can constantly say "Oh i'm
gonna run quicken to EOT this." ...Don't be that
guy. Hypersonic dragon.... sure, maybe.
otherwise, don't try it. Anyway, this breaks one
of my golden rules of magic "If it's going to
give your opponent a chance, don't play it." Hug
cards aren't worth it. Especially one like this
that gives your opponents first dibs if you're
playing it straight off during your turn. No,
thanks.
