There was no obvious sign as to what triggered this but I have formed my theory as to how this occurred with no way to recreate it.

Opponent Summoned Aleister the Invoker, added from deck Invocation to hand.
Opponent’s turn proceeded until end, I believe with no other cards added to hand, or with invocations effect in grave adding Aleister back from banished to hand I can’t remember.
My turn occurred, proceeded with other events happening, turn ended.
My opponent Drew for turn an Invocation and the game revealed it to me as if he had added it to hand.

I believe this would work with any card that is added to hand by a card effect, placed on the top of the deck, and drawn for the next draw phase (or perhaps even any draw). I do not know how to recreate this scenario so I have not attempted to recreate it.
This was the only draw that was revealed to me.

If a card is revealed and put on top of deck (not shuffled), the opponent already knows what card it is. Also note this is the case for all ygopro simulators that when you add a card from deck to hand, it is revealed until you shuffle the hand. In our sim, the hand is auto shuffled for this reason.

In Duel Links, they also have a log. If a card is revealed already, then it will be in the log. Visually, hence, it won’t matter if you block or not since the log is there. This is also the same case for face-down monsters that were already revealed.
