mobilize cards mtg (Card) and it becomes a Vampire in addition to its other types. MOBILIZE - Death by 1000

An Ob Nixilis thats actually a great demon commander

I believe this came about because they wanted a mischievous creature on the back that punished the opponent for not having enough cards in their hand, and flavor-wise, that felt a lot like a faerie (it was an imp when it was on Equilor)

In fact, I know you can, because the other commander for the Tyranids is already much higher on this list

Thorna and Twigtooth is an aggressively costed Arena-only commander, sadly you won't remove many stun counters with its attack trigger, but otherwise, any cool drawback counters you want to get rid of become a huge advantage for you

Casual players love cards like this
