Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If you have a "Gate Guardian" monster in your GY: Pay half your LP; Special Summon 1 Level 11 or higher "Gate Guardian" monster from your hand, Deck, or Extra Deck, ignoring its Summoning conditions. You can banish this card from your GY; add 1 of your "Sanga of the Thunder", "Kazejin", or "Suijin" from your Deck or banishment to your hand. You can only use each effect of "Dark Element" once per turn.
