I chose Oakhame Adversary as my card of the week as I am increasingly including it in decks.
Oakhame Adversary fails the vanilla creature test due to its Mana Value of 4 (3G) and it’s stat line of 2/3 but it makes up for this with multiple lines of rules text. The first one is what makes Oakhame Adversary such a good card because it comes with it’s own cost reducer. If an opponent controls a green permanent it costs 2 generic mana less to cast, meaning that you can cast it for 1G. In a four player game of commander it is likely that an opponent will have a green permanent.
The next two abilities are very synergistic as it has the keyword Deathtouch and when it deals combat damage to an opponent draw a card, if you give it double strike you would draw 2 cards. Creatures with Deathtouch are always problematic as it will require your opponent to throw a creature in the way or use a piece of interaction and you can always use it a deterrent to stop attacks.
It’s creature types being Elf and Warrior are also advantageous as Elves are the representative race for Green and have many tribal commanders, and there are multiple warrior payoffs and tribal commanders.
Add in the fact that it draws you cards and can do so consistently over a number of turns and you have an absolute gem of a card.
Some of the decks Oakhame Adversary could go in include: Fynn, the Fangbearer; Najeela, the Blade-Blossom; Lathril, Blade of Elves; Ezuri, Renegade Leader; Marwyn, the Nurturer; Rhys the Redeemed; Freyalise, Llanowar’s Fury; Prossh, Skyraider of Kher… Basically any deck that has Green.
