Jade Pillar is a Location in the Beyond the Doors set.
Geography[]
Jade Pillar is one of the many Pillars supporting the UnderWorld ceiling. It appears to be composed of green crystal which is mined by UnderWorlders, with scaffolding constructed around the structure to get at the upper sections.
Strategy[]
Jade Pillar is a highly risky Location to run in most decks, as combats in this Location turn into contests of manipulating Attack damage. Not being able to avoid dealing damage can be a severe detriment by causing its damaging effect to trigger on yourself; as such, it should be avoided in most decks that make heavy use of damage modifiers.
UnderWorld decks often have high Power, which lets them win Initiative easily, and as long as you have enough 0-damage Attacks to avoid triggering its ability yourself, the huge damage it deals can be good for supplementing a burn-based strategy. Conversely, Mipedian decks built around high Strike damage will often find themselves unable to avoid taking damage from Jade Pillar, making it a decent tech against Mipedians in UnderWorld decks.
Past decks with Smildon and Ursis can also use this card, as Smildon can wipe this card's effect if you can't avoid triggering it on yourself.
