One of those ideas was to stretch the art across two cards
Edric, Spymaster of Trest Edric, Spymaster of Trest leverages blues many unblockable creatures, like Mist-Cloaked Herald and Slither Blade, to slip through your opponents defenses and rip through the deck to chain together extra turn spells, and eventually conclude the game with a Beastmaster Ascension or something
You pay, say, four Black mana and exile Ob Nixilis, Unshackled
Fortunately, Slogurk doesnt care how your lands get to your graveyard, making this task easy
So many of these could have easily made the Top 20, but considering A) that would have skewed the 20 into a list of most easy to include in all of your decks and B) would have taken multiple slots away from other cards, theyre also getting an Honorable Mention
Plus, you can pay three mana and exile it to give a legendary creature hexproof and indestructible until the end of the turn
