Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
1 Tuner + 1+ non-Tuner monsters If this card is Special Summoned: You can add 1 Spell/Trap that mentions "Crimson Dragon" from your Deck to your hand. (Quick Effect): You can target 1 Level 7 or higher Synchro Monster on the field, except "Crimson Dragon"; return this card to the Extra Deck, and if you do, Special Summon 1 Dragon Synchro Monster from your Extra Deck with the same Level as the targeted monster. (This is treated as a Synchro Summon.) You can only use each effect of "Crimson Dragon" once per turn.
