Keep in mind that if all of the cards in a deck are marked in the same way, such as with a small bend on the corner of the sleeve on all of the sleeves, the deck and the cards are not considered marked
With Marneus, this not only generates massive card advantage but also provides strategic utility by copying impactful creatures like [[Thassa's Oracle]] or mana dorks
A lot of my opponents will draw for turn prior to remembering to pay the 4 for Paralyze, getting a big advantage off of that added information
I'd argue that Y'shtola falls in the "too strong" category and not a fan of how power-creepy it is, but it's hard to deny that this will excite a lot of players who like obviously powerful commanders
Korvold, Fae-Cursed King Korvold, Fae-Cursed King is one of those commanders that turns every small sacrifice into pure value
There's no better time for your first Magic game than now
