yugioh obelisk the tormentor card (Anime Art) - 8 cards set and you can negate a monster’s effect and destroy it without needing to Tribute Obelisk the Tormentor (Ghost Rare)

There are some commanders printed that incentivize you to attack players either with their own stolen creatures or with creatures you control but dont own

Costing less than most board wipes, Flatline lets you potentially power through your opponents creatures with devastating efficiency

Its nice growing creatures with combat-relevant abilities, and double strike is one of the more relevant ones

Costing one less than Phyrexian Arena makes it much easier to cast another spell that same turn, and it turns out having a ring-bearer is actually very good
