Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
While you control a Level 7 or higher "Ancient Warriors" monster, your opponent must pay 400 LP to activate a card or effect. You can only use each of the following effects of "Ancient Warriors - Savage Don Ying" once per turn. If this card is Normal or Special Summoned: You can add 1 Level 7 or higher "Ancient Warriors" monster or 1 "Ancient Warriors" Continuous Spell/Trap from your Deck to your hand. If a monster is sent to your opponent's GY (except during the Damage Step): You can target 1 card in your opponent's GY; banish it, and if you do, draw 1 card.
