Monitor Monitor
When this creature enters, open an Attraction. (Put the top card of your Attraction deck onto the battlefield.)
Once each turn, you may pay 
to reroll one or more dice you rolled.
Nine fires, a hull breach, and a Quafloovian meganibbler escaped from the petting zoo. Things were suspiciously quiet.

If you roll multiple dice at the same time, paying
will let you reroll any number of those dice. You don’t have to pay per die.If you control multiple Monitor Monitors, you may use each of them once each turn. You may use multiple Monitor Monitors on the same die roll if you wish.
You decide whether to use Monitor Monitor’s ability right after you monitor the result of the die roll. You can’t wait and use it to reroll that die later.
You can use Monitor Monitor’s reroll ability on any die roll, including a roll of the planar die in a Planechase game.
