"Power level of this deck will hopefully be in the 6-7 range, but being mono-white means that this deck is mostly "fair" when compared to other decks at most tables."

I apologize if this is off topic, but what scale is this power level using? Do you have a link or is this defined anywhere? I've had issues in the past with other players in my group having wildly different power levels and I think having a scale might help with that.

Also, as to the deck...

A personal favorite of mine is Spirit Link it can shut down an opponent's creature. (If they deal damage to you, you regain it as life) It also still allows them to attack other players. Alternatively, you can place it on one of your own creatures.

Not gonna lie, I was just kind of guessing on power level. I dont usually use any sort of guide, just some (somewhat) educated guessing. I did recently find that Beebles has a power level guide on his profile page that I've started using as a basis. It's really helpful!

Thanks for the reference! Just for clarity: I did not create it. I’ve now added the source to my page + some context.
