This is the answer in case Propagate decks get
out of control (and its existence is probably
why they won't). It does everything Oblivion
Ring can do, it can't be undone by an opponent
with the same card, and it takes out any
duplicates. You can instantly wipe out a token
army, or simply deal with whatever's most
bothering you and so what if you don't get any
other copies.
Things get interesting if you and your opponent
have copies of the same card-- you can't take
out your opponent's without also taking out your
own. Or, if you can't target your opponent's for
whatever reason, you can still take out your
opponent's by targeting your own.
I assume the main reason this exists is because
they didn't like the fact that you can exile an
Oblivion Ring with a second Oblivion Ring and
set up bizarre, unintuitive changes of Rings
within Rings within Rings (and not a Lord in
sight). I feel obliged to point out that that
sort of thing happens less often in singleton
formats. Of course, it's also strong against the
Selesnyans' token-heavy strategies, and is only
very slightly harder to cast than its famous
ancestor. I don't doubt that this will be a
go-to card in high-level decks with both white
and blue, and as the block's variant on Oblivion
Ring it will be one of the defining cards in
limited and block constructed.
Today's card of the day is Detention Sphere
which is a three mana Blue and White aura that
exiles target nonland permanent not named
Detention Sphere and other permanents that share
the name and when it leaves play it returns the
cards to the owner's control. This is very
similar to Oblivion Ring with Maelstrom Pulse
flavor that removes the interaction between
multiple Oblivion Rings. The multicolor
aspect keeps this from being as flexible as the
Ring, but the benefit against tokens and
multiple copies of cards compensates for that
noticeably. Overall this will be a popular
card in Blue/White decks, very likely maindecked
or at least sidedecked for token swarms.
In Limited this is a great removal option for
Azorius that should always be included as a
weapon against tokens or any single threat that
needs responding to. An easy first pick in
Booster and splashable for Sealed when the
chosen guild shares a color.
Welcome to another great card of the day review here at
Pojo.com! Today we are looking at Detention
Sphere from Return to Ravnica. Detention Sphere
is a rare blue and white enchantment that costs
one generic, one blue, and one white mana.
Detention Sphere says when it enters the
battlefield, you may exile target non-land
permanent and all cards with the same name as
the targeted permanent, as long as they are not
named Detention Sphere. When Detention Sphere
leaves play, return the exiled cards to the
battlefield under their owners control.
Mass removal. That is what this is meant for. Like Oblivion
Ring, it exiles something on the board for so
long as the enchantment remains. Unlike O-Ring,
if there should be multiple copies around, they
all go into exile for as long as the Detention
Sphere is out. While this is really useful, I
find that perhaps what it is best suited for is
a major blow dealer to token decks. Since they
are permanently exiled by this, bouncing it
around is nothing short of a nightmare for a
token deck.
Outside of that, it is just as good as Oblivion Ring with a
boost.
