Magic Minigame: Roll for Initiative!

• 2 or more players • 1 or more packs • 5 minutes • d20
Objective:
As you enter the room,. the terrible dragon open its eyes and lets out a roar. Everybody...roll for initiative! Roll a d20 and modify the result with some Magic cards to get the highest initiative!
Get Ready:
Open a booster and remove all cards without Magic card backs. Use an additional booster for groups of five players or more. Shuffle, then deal the same number of cards to each player. If there are extra cards after dealing, set them aside. Each player then rolls a d20 to determine their initiative. In case of a tie, the tied players roll again. The player with the lowest starting initiative goes first.
Let's Play:
On each player's turn, they play a card to modify a player's initiative (see reverse side for card effects). Card with effects that will be counted at the end of the game should be placed in front of the target player. All other card go into the discard pile.
Play continues until all players are out of cards.

Multicolored card: Apply the effects of each of the card's colors. Each effect can target a different player.
Any Card Played Face Down: At the end of the game, increase or decrease a player's die roll by 1.
