Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can discard this card; add 1 "Lair of Darkness" from your Deck to your hand. You can Tribute 1 DARK monster; draw 1 card, or, if you Tributed a DARK monster other than this card to activate this effect, you can add 1 DARK monster with 2000 or more DEF from your Deck to your hand, instead. You can only use this effect of "Ahrima, the Wicked Warden" once per turn.
