It is a relatively interesting list as it is far more subject to opinion being that it is not just my opinion but my opinion of other people's opinions

Four mana is a massive cost, a creature has to be Titan levels of good or you have to have vast amounts of spare mana before you are paying it

We also want topdeck manipulation (Brainstorm) and high cmc spells (Ulamog, the Infinite Gyre) but we can cheat a bit on the high cmc with cards that have alternate casting costs (Snuff Out)

As I have done more of these top X lists it has felt ever more pertinent to compare stricter categories as it is much more useful for cube design, deck construction and understanding the things that make those kinds of cards good
