What exactly do you mean by "REL level 2"? I assume you mean Competitive REL, because that is the middle in terms of strictness out of the three levels.

@murgatroid99 Sorry I was mixing up judge levels and REL levels. That is correct that I meant Competitive and Professional REL. Thank you for clarifying that.

I was reading the card [Chains of Mephistopheles](https://gatherer.wizards.com/Pages/Card/Details.aspx?name=chains%20of%20mephistopheles) and I found these great [flow](https://i.sstatic.net/nImv9.jpg) [charts](https://i.sstatic.net/HeLTN.png) for how it's replacement effect works. Would I be allowed to bring a simple flow chart like that to a sanctioned event? Would this change if the event was Competitive or Professional REL?
