It's easy to make mistakes when evaluating cards
like this. One I've seen in the past is
comparing it to Tinker, without stopping to
consider that Tinker is in From the Vault:
Exiled and there's a reason for that. Fabricate
is a powerful card for casual play or any less
powerful format where you rely on a specific
artifact - I recommend Darksteel Reactor, but
you have many, many fun options with this.
Today's card of the day is Fabricate which was
last seen in the Mirrodin set. It is a Blue card
in the spirit of Tinker with the changes of not
sacrificing an artifact or putting a new one
directly into play. While not having the sheer
power of turning an Ornithopter into any
artifact you want, it still offers a useful
Tutor effect. Plus when combined with Master
Transmuter you have a two card Tinker that is
legal in Standard and merely returns the
sacrificial artifact to your hand.
In Constructed and Multiplayer this is a card
that can be used to search out any important
artifact needed at the time and have it be
appropriate to the situation you are in at the
time. Blue often uses an artifact theme, as seen
with the Esper shard and the Tezzerator deck
concept, and this can be a welcome addition to
that.
For Casual I am giving this a bit more attention
as the format really lends itself towards very
specific combos and singularly powerful cards.
Using something to search them out makes a
casual deck more stable and even more
importantly helps keep the focus of the deck
visible to the opponents.
With Limited the reduced number of available
artifacts that are useful and worth searching
out is drastically reduced. Unless you happen to
draft a really powerful artifact you absolutely
must have another chance at drawing I'd pass it
in Booster and keep it in Sealed's sidedeck.
Also, keep in mind even if you do have a great
artifact you actually should have at least one
other decent choice in case you draw the
artifact before drawing Fabricate. Without a
second choice this is an utterly dead draw that
would only grant you the ability to shuffle your
deck for three mana which is not a very
impressive topdeck late in the game.
