Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
(This card is always treated as a "Galaxy-Eyes" card.) Pay half your LP, then target 2 monsters in your GY; Special Summon both, but negate their effects, then, immediately after this effect resolves, Xyz Summon 1 "Number" Xyz Monster using only those 2 monsters, also for the rest of this turn after this card resolves, you can only Special Summon one more time from the Extra Deck. You can only activate 1 "Numbers Last Hope" per turn.
