If a card only depends on another card, it it situational. We don't have any of those cards yet, and even at that state we already have some cards that are not too reliable because the use is too situational, and we all know that flooding is one of those. If one card depends on another card, it won't have any use in other decks. Yes, it is situational because you have to use it in a deck than can be countered by flooding AND in a deck that will benefit from this.
