Mistress Fanchon's special

Does Mistress Fanchon's controller need to reveal to other players which minion card she pulled from her controller's library? It doesn't say she does, but how are other players supposed to know whether her controller pulled a minion card rather than a master or event card? Her ability just seems to be begging people to cheat. Sibyl's Tongue explicitly says that you must reveal it to others. Really her ability needs to be changed to require that you show others which card she pulled from library. But I'm wondering if there is some ruling already that I don't know about. Can I get a ruling?

Mistress Fanchon
Tremere

Capacity: 11
Group: 4

Camarilla Tremere Inner Circle: Mistress Fanchon may search your library (shuffle afterward) for any minion card and move that card to your hand as a +1 stealth action. +2 bleed.

Sibyl's Tongue
[Action] Action

[Malkavian antitribu] Malkavian antitribu

[X Blood]

+1 stealth action.
This action costs X blood, where X is the number of Sibyl's Tongues in your ash heap. Choose a card by name. Search your library for a copy of that card, show it to all players, and move it to your hand. Discard down to your hand size and shuffle your library afterward.

You can always call a judge or play with people that do not cheat.

Who said anything about cheating? Honest mistakes happen, and it is quite easy to make one on this effect. Can you even guarantee that you never did it yourself, since nobody ever double-checked your play?

It would be strange not to have anyone around that can justify that the card is a minion card. You can also ask the player "it's a minion card, right?" if you want to be sure.

When you are playing on Lackey, you don't have someone to justify the card is a minion card. This is where the discussion came up that prompted me to ask here.
