Thieving Moriok - :1mana::symu::symb:
Creature -- Human Minion (R)
When Thieving Moriok comes into play, you gain control of target Equipment.
If you paid the kicker cost, gain control of target artifact instead.

Remove all equipment attached to and enchantments enchanting target creature from the game. At end of turn, return all removed cards to play enchanting and attached to that creature.
Game of Chance - :4mana::symr:
Each player chooses a permanent another player controls.
Each player reveals the top card of his or her library. The player who revealed the card with the highest converted mana cost gains control of all permanents chosen.

Thieving Moriok = Looks pretty good. Could be straight blue if you wanted, though as a Moriok it makes sense to have some black in the cost.
Samurai Strategist = Funny. I like it.
Rune of Truth = Cool. Drop the cost to W.
Game of Chance = Nice.
