Grikk the Gremlin is a promotional Character card for Witchful Thinking. Grikk's first Character Ability, Mischievous, represents every gremlin's instinct of ruining peoples lives and sabotaging their dreams. This Character Ability allows Grikk to force a witch to swap 1 Potion card of his choice with him or another witch when he plays a Sneaky Witch card. In Witchful Thinking, the winner of the game is the player who has collected the most Potion cards. If there is a tie, all tied players must add their own Potion cards together, and whoever has the greatest value wins. This means that players want Potion cards with positive numbers instead of negative numbers to ensure their own victory. So for example, if a witch has the Elixir of Life which has a value of +18, Grikk can use his Character Ability to take that valuable card away and give it to another witch instead, or he can take it for himself. Grikk's second Character Ability, Trickster, represents every gremlin's desire to play tricks on others. This Character Ability allows Grikk to force a witch to swap their entire hand of Ingredient cards with another witch or himself when he plays a Sneaky Witch card. Forcing other players to swap their cards with each other can be a useful tactic because you can interrupt what the players were planning to do next. Alternatively, Grikk can use this Character Ability to get new cards if his own cards are no good.
