Vigilance
Whenever a creature you control enters, if its power is greater than this creature's power or its toughness is greater than this creature's toughness, put a +1/+1 counter on this creature and investigate. (Create a Clue token. It's an artifact with "{2}, Sacrifice this token: Draw a card.")

Vigilancia.
Siempre que una criatura entre al campo de batalla bajo tu control, si su fuerza es mayor que la fuerza de la Novata observadora o su resistencia es mayor que la resistencia de la Novata observadora, pon un contador +1/+1 sobre la Novata observadora e investiga.
