This is primarily due to the cards scarcity, appearing only in the Forces of the Imperium Commander Precon

Threshold This creature has protection from green and from white as long as there are seven or more cards in your graveyard

One way is to pair it with Coretapper and Magistrate's Scepter, or you can attach Helm of the Host to Combat Celebrant to get infinite combat steps
