Searching Commander's cards in the deck

[JahSper]

If one ability, such as "The Rightful Queen", allows you to search for a Commander's card in your Tactic Deck, are you supposed to fully show the card to your opponent? Or should you only show the upper-left corner with the picture of your commander in order to disperse any doubt that you have just picked an elegible card? Or is there another procedure that is considered to be correct?

Thank you in advance.

There is nothing that requires you to reveal a searched card to your opponent. The text would directly tell you to reveal the card if it was meant to do so.

If you believe your opponent is cheating by taking an incorrect card, then it should be handled in the same method as if you believed your opponent was cheating in any other regard.

In this specific instance, if you want to verify by showing the Commander image, that would be an easy way to do so, but again, that falls under the umbrella thinking of "I believe my opponent would/is cheating".
