Artifact Creature â Wall
You may tap an untapped Wall you control to have any player reroll a die that player rolled.
You decide whether to use Wall of Fortuneâ€™s ability right after you see the result of the die roll.
You can use Wall of Fortune to have a player reroll any die, including the planar die or the d20 from Sword of Dungeons & Dragons.
The Wall you tap to use Wall of Fortuneâ€™s ability can be one that came under your control this turn. This includes Wall of Fortune itself.
If a player rolls a die, you can tap an untapped Wall you control to have that player reroll that die. Then, if you didnâ€™t like that result, you can tap another untapped Wall you control in order to have them reroll again.
