If this card is Link Summoned: You can discard 1 card, then target 1 card on the field; shuffle it into the Deck, also if this card was co-linked at activation, you can draw 1 card. You can only use this effect of "Knightmare Unicorn" once per turn. While a co-linked "Troymare" monster(s) is on the field, draw cards equal to the number of those monsters with different names instead of 1 for your normal draw during your Draw Phase.
