Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Activate 1 of these effects. ● Discard 1 card; add 2 "Machina" monsters with different names from each other from your Deck to your hand. ● Discard 1 "Machina" card; add 2 "Machina" cards with different names from each other from your Deck to your hand, except "Machina Redeployment". You can only activate 1 "Machina Redeployment" per turn.
