When ranking these commanders, I did my best to evaluate how good I think they are specifically as commanders, not just as cards in general
In terms of gameplay, a Foil Magic The Gathering card against a regular Magic The Gathering card has no difference
It is also an uncommon card, which keeps the aggro decks under budget and that's a huge factor
They arent for every sacrifice deck, but the burst of card draw makes them quite useful, especially if you can recur the sacrificed creature for further value
I spent a good amount of time thinking through this and making my arguments
However, by adding some additional effects to the card especially the part where your opponent loses 2 life --- it makes it so this Mind Rot actually does something even late
