Let's look at a few discard spells and rank their fun, shall we
Archfiend of the Dross is an impressive creature, a flying 6/6 that only costs four mana, it even has an additional useful life drain ability
It has both versions of the characters and works best when it uses its supporting cards and Equipment to buff Legolas and Gimli and remove enemy creatures from the battlefield
I enjoy him as a Golem theme deck, weird tokens (ala Brudiclad, Telchor Engineer deck, or any kind of weird intersection therein, but the aristocrat was the most fun for what it is
That said, I saw someone say that this set made them finally want to watch Cowboy Bebop and reading that did an amount of psychic damage to me that can't be repaired
The early Standard environment right now is getting dominated by both Ob Nixilis and decks playing heavy control elements with Meathook Massacre
