Welcome back to the Knowledge Pool. This week we have another Silver scenario. L2s should wait until friday to join the fun.

You're the Head and only judge of a Modern PPTQ. Arielle is playing against Nice. Arielle controls a Liliana Vess and he activates Liliana's -2 ability, searches and finds a card. She then shuffles her library and puts that card on top of it. Arielle then attacks with a Grim Haruspex, and Nick blocks with a Tarmogoyf. They go to combat damage, both creatures die, then Arielle says “draw for Haruspex” and draws a card immediately. Nice reads Grim Haruspex, points out that the card shouldn't have been drawn, and calls a judge.

What do you do?

We have a simple HCE in this case, as said in the additional remedies in the IPG, the owner knew the identity of the card, so it should be returned to the library and not shuffled.


From IPG 2.3 GPE-HCE-Additional Remedies

If a set affected by the error contains more cards than it is supposed to contain, the player reveals the set of cards that contain the excess and his or her opponent chooses a number of previously unknown-cards sufficient to reduce the set to the correct size. These excess cards are returned to the correct location. If that location is the library, they should be shuffled into the random portion unless the owner previously knew the identity of the card/cards illegally moved; that many cards, chosen by the opponent, are returned to the top of the library instead.

Issue Arielle a Warning and apply the fix as follows, Arielle reveals her hand and Nice chooses one card from there to be put back into the top of Arielle's library.
Remind both players to read their cards carefully.

A bit slow this week, but Herbert has got this one right away.

Issue Arielle a Warning for Hidden Card Error. Arielle reveals her hand and Nice chooses one card from there to be put back into the top of Arielle's library. Remind both players to read their cards carefully.

Herbert points out the exact clause we are looking for. Since Arielle knew the identity of the card, it gets put back on top instead of shuffled in.
