Themes for Karlov of the Ghost Council
Voltron
Voltron decks focus on commander damage or a few creatures and turns them into massive, protection-from-everything kind of creatures and finishing off the opponents in combat.
Aristocrats
Aristocrat decks are a combination of sacrifice effects, reanimating and value creation. Wincons revolve around multiple triggers, either from dying, ETB or cast triggers.
Lifegain
Lifegain is one of the the most popular themes in EDH. Multiple triggers to gain life and value received from the lifegain triggers are really fun to follow as a player. Often lifegain is combined with another theme, +1/+1 counters or creature tokens, as pure lifegain is often not powerful enough to win the game.
Combo
Combo decks are control heavy decks, running a heavy amount of card draw or tutors. If the decks get to assemble the combo pieces the game often ends in an infinite combo.
+1/+1 counters
White has many great support spells and permanents for +1/+1 counters theme. Counters theme is often combined with White-weenie or token strategy and turns the small creatures into a formidable force.
