It took me a long time to figure out what was
going on in this card's art. Once I did, though,
I decided it was a suitably sinister and scary
piece for a card that may end up being
disruptive and feared by players. While eight
cards is a lot to ask for the maximum
delve-related discount, cost-reducing mechanics
were made to be abused, and blue is perhaps the
color best equipped to use delve (cf. Gitaxian
Probe, Hedron Crab, Wistful Thinking, etc). It's
risky to discount a Power Nine effect at any
mana cost - consider that Time Warp was
considered too good for Standard at a mana cost
of five.
Today's card of the day is Temporal Trespass which
is an eleven mana Blue sorcery with Delve that
has you take an extra turn and exile Temporal
Trespass. This is a card that truly relies
on Delve to be effective as it can lower the
casting cost to three, which is a bargain to
take an extra turn. This can be used in
self-milling strategies or just a later game
trump card for the major advantage it offers.
Overall a very solid card that will be popular
in multiple formats.
In Limited this is a tempting first pick in
Booster that is difficult to pass both for the
potential advantage it can give you and the risk
of letting another player having access to it.
The heavy reliance on Delve and triple Blue in
the casting cost relegate it to the later stages
of a game, but the power mostly outweighs those
disadvantages. In Sealed it is not quite
enough to force Blue as the primary color, but
if the pool is strong and makes up half the deck
or more it should absolutely be included for the
huge advantage taking an extra turn can be.
