Our goal as magicians is to replicate reality as closely as possible & to always be directing the audience in every time they laugh, question, assume, look away, look closer, reacting, etc...
Using an object that's not easily recognizable will always bring questions & will detract from your desired effect if you are not prepared for that. In today's time since most card games are played online, we're more than lucky if laypeople are familiar with traditional Bicycle playing cards.
Which is why you will find spectators who assume you're using trick cards are the ones most unfamiliar with playing cards & it's our job to initiate them with the cards before we begin to perform by letting them shuffle & handle the cards & even talking about the values & suits.
I have found when I perform for people who are familiar with poker, black jack, and familiar with handling cards in general are the last ones to suspect you're using gaffed cards if you designate the right approach.
