Shocking Transformation has always been a nice card: featured in two World Champions decks (Shock and Awe and Drained Domains of Doom), with a long history of reliability, sturdiness and general power, it deserve some attention and, despite my lack of knowledge, an article.
Here's the card.
========== Shub-Niggurath ==========
Type : Event
Cost : 3
Game Text: Action: sacrifice one of your characters to search your deck for a non-Ancient One character and put it into play. Then shuffle your deck.
Collector's Info: UT U121
Now, what does Shock do? Basically it lets you play at Event speed (that means as soon as your opponent has brought down that pesky Yig, or after he has commited is chars no the offense, or after he has started his evil combo of doom) any non-ancient one character, provided you have at least another one on the boards.
How to use it.
Accelerator. It might not be the best use for the card, but sacrificing a cannon fodder to get out a fatty earlier should not be underestimated. You could Shock a Ghoul Khanum in play or a Professor of Archeology and have their cost lowered by 3 or 2. Not a bad deal, but one of the least efficient use of the card.
Tricks and Traps. Shocking into play a refreshed character during unexpected times (say, after your opponent has committed in his turn) might bring you good fortune. And none say the character is not some roadblock like Ravager from the Deep or Bestial Shoggoth.
Searching. Sometime you really need that Mentor of Vaughn surreptiously hidden in the last 10 cards of your deck. Sometimes you just want to seal the deal with a Messenger from the Spheres, but can't draw him for your life. Or your evil combo just lacks that Ancient Guardian that's avoiding getting drawn like he is limelight shy. Here Shock comes to the rescue and lets you search in your whole deck. Combined with 1 this makes for some early potent rushes. But using this jewel for rushing is probably the worst way to employ it. A recent game with an extremely talented player showed me that Shock shines as a Control player card.
A big bonus of Shock is that it becomes inherently stronger the more strong characters are published, so investing in a good Shock deck will seldom leave you torn between playing this or that faction for resource match with the new wundercard.
911. Emergency call. This versatile card allows you to mimic a wide range of event speed actions through responses in shocked characters. A staple of this strategy has been using Shocking Transformation, after your opponents play some mean but vulnerable character (Yig or Ithaqua, for example), to field T-Men. The accountants with guns will just storm the place, kill that pesky GOO, and offer their neck for further sacrifice. Maybe another shock.
But Shocking T-Men isn't the only 911 call you can make. Shock interaction with Elder Thing allows you to ready for recycling two used cards (which might incidentally be the Shocking transformation you just used). Bonus points if you manage to start an Elder Thing Assistant cycle to get back your Shocks every turn.Hard Case and Victoria Glasser earn a minor in 911 too.
Fetching fetchers. Now, Shock has some limits. Namely that it can't search for Ancient Ones, it cannot search in the discard pile and that time I tried Shocking in Beyoncé it didn't really perform. Guess she is either a Great Old One or my copies of Shock are somehow faulty.But Shock is a team player, an awesome buddy and will never let you down. Need an Ancient One? Shock Lavinia Whateley in play and hurry fetching that Ithaqua! Need that awesome Nyarlathotep lying unused in the discard pile? Shock in an Hungry Dark Young.
Pretty awesome, isn't it? Now, Shock me with your ideas on how to exploit it.
