Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
This card can be treated as 2 Tributes for the Tribute Summon of a Dragon monster. You can banish this card from your GY, then target 1 Level 5 or higher Dragon monster in your GY; add it to your hand, then, immediately after this effect resolves, you can Tribute Summon that monster. You can only use this effect of "Samsara Dragon" once per turn.
