Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can reveal this card in your hand; banish (face-up) 1 random face-down card from your Extra Deck, then, Special Summon this card if the banished card was a Link Monster. Otherwise, discard this card, and if you do, draw 1 card. You can only use this effect of "Link Apple" once per turn.
