I was bored.
I noticed that four of my d20s match the UNO colors.
So I started brainstorming ideas for a D&D UNO! themed deck, similar to how the Ubisoft UNO DLC Decks add in new action cards to shake things up a bit, this Dungeons and Dragons UNO! deck idea is more than a theme to add imagery to the cards.
So yea, D&D UNO! gives players the standard rules, plus each player gets a d20 (one red, one blue, one green, and one yellow), and there are some new cards added to the deck, and a new rule.
THE NEW RULE - "WILD ROLLS" - Whenever a Wild Card of any kind is played, the player no longer selects what new color will be. Instead, all four players will roll their d20s. Whichever d20 rolled the highest will become the new color for the pile. So if the player with the red d20 rolled the highest, the color shifts to red and the turn rotates to the next player in line.
Let chaos follow suit as players have less choice in what cards they can strategically play.
NEW ACTION CARD No.1 - "PETTY SACRIFICE" - Play this card to grant you the ability to discard one more of your cards and place it at the bottom of the pile; essentially this card acts as a Draw -2, allowing you to rid your hand of two cards in a single turn rather than one.
NEW ACTION CARD No.2 - "COUNTER ACTION" - If a player lays a Draw 2 or a Wild Draw 4 onto you and this card is in your hand, you can make a risky move. Challenge the player and the both of you will roll your dice. The one who rolls lower is the one who has to draw the cards instead, so if you successfully countered, you get to play your turn as normal while the person who wanted you to draw now is the one to draw cards instead!
NEW ACTION CARD No.3 - "DODGE ACTION" - The player before you has placed a Draw 2, a Draw 4, or a Skip card. But with this card in your hand, you can instead "dodge" this attack and have it land on the next person in the rotation. If Draw2/Draw4 stacking is allowed in the match, this dodge can be avoided by the person placing a Draw2/Draw4 in order to make the 4th player in the rotation Draw4/Draw8 instead.
NEW ACTION CARD No.4 - "PICKPOCKET" - When played, all other players have to roll their dice. Whoever rolled the lowest is the one that you get to choose to steal a card from and make it your own. YOU DO NOT GET TO SEE THE TARGET PLAYER'S HAND SO THE PICK IS RANDOM. However this move is a bit risky as it can end up with the player having the lowest dice roll having only one card to begin with, meaning that even though this other player would be normally unable to play their card (they have a blue but the pile color is currently yellow), you accidentally let them win the round.
NEW WILD CARD No.1 - "DECK OF MANY THINGS" - Once all players have rolled their dice and the color has been changed to match the color of the one that did the highest roll, the player who rolled the lowest number has to draw two cards from the deck. This is somewhat of a risky card however, as it can backfire and cause the person who played it to be the one to draw two cards as they may be the one to roll the lowest.
NEW WILD CARD No.2 - "WILD D20" - A trap card! Whoever draws the Wild d20 from the deck is forced to play it. All players roll their dice to determine the new color to be. Then all players must draw 5 cards from the deck (resulting in 20 cards drawn for a standard four player match).
If a player manages to roll a Nat20 with their dice, they get to choose only one player to draw five cards while all others get off scott free, and whoever rolled the Nat20 gets to play a card from their hand to the pile. This action does not skip turns in the rotation.
THERE IS ONLY ONE "WILD D20" CARD IN THE DECK
When it is played, it is immediately put back into the deck and the deck is reshuffled.
And there you have it.
The Number Cards are based on the traditional races/classes you can play in D&D, the Action Cards are some of the more iconic monsters you can face in D&D, and the Wild Cards are each a form of Chromatic Dragon, with Wild Draw 4s being Tiamat, the Wild "DECK OF MANY THINGS" cards being a Mimic Chest, and the "WILD D20" card being a simple black wild card with a multi-colored d20 depicted in the center.
