Vintage Control Slaver deck

The primary focus of Control Slaver is Mindslaver. It can be either "hard casted" or brought into play with Goblin Welder. The deck typically only needs one activation to put the opponent at a significant disadvantage, but can recur it with Welder if necessary. Once it has solidified control of the game, the deck typically wins with a large artifact creature such as Darksteel Colossus, Pentavus,Sharuum the Hegemon or Sundering Titan.

Early days
Control Slaver was first seen in tournament play at Duelmen on Dec. 21, 2003, played by Kim Kluck of Team CAB:

Two schools
Then two schools emerged: Control Slaver (also called Drain Slaver) based around the list above, and Workshop Slaver, which has no permission.

Here is a list of Workshop Slaver, played by Kevin Cron on Mar 13 2004:  Lands 2 Ancient Tomb 4 Mishra's Workshop 4 Shivan Reef 1 Tolarian Academy 4 Volcanic Island

Creatures 4 Goblin Welder 1 Memnarch 1 Pentavus 1 Triskelion

Artifacts 1 Black Lotus 4 Chalice of the Void 3 Gilded Lotus 1 Mana Crypt 1 Mana Vault 1 Memory Jar 3 Mindslaver 1 Mox Emerald 1 Mox Jet 1 Mox Pearl 1 Mox Ruby 1 Mox Sapphire 1 Sol Ring

Instants 1 Ancestral Recall 4 Brainstorm 1 Fact or Fiction 4 Force of Will 4 Thirst for Knowledge

Sorceries 1 Wheel of Fortune 1 Timetwister 1 Tinker 1 Time Walk

Sideboard 3 Blood Moon 2 Gorilla Shaman 2 Rack and Ruin 4 Red Elemental Blast 4 Trinisphere

Control Slaver proved to be better that Workshop Slaver whose appearances dwindled. Control Slaver was a common deck in the Top 8 of major tournaments around 2006.

Modern designs

Restriction of Thirst for Knowledge and resurgence
After the restriction of Thirst for Knowledge</c> in June 2009, Control Slaver disappeared for several years as a Vintage archetype. It has seen some amount of resurgence since September 2015, after Thirst for Knowledge</c> was again unrestricted at the same time as the dominant Workshops deck took a hit from Chalice of the Void</c> being restricted. Modern Control Slaver decks may choose to downplay the number of Goblin Welders</c> in the Mental Mistep</c> era of Vintage.
