During yesterdays GPT, one situation arose where I was confident in my ruling but was later challenged by one of the players.

Player A has a Salvage Drone in play, which player B kills. Player A draws a card from Salvage Drone's ability, but doesn't discard a card. Play proceeds to Player B's turn, and then to Player A again. At this point the players become aware of what has happened and calls for me.

I rule that it is GPE-DEC and since none of the examples in the IPG apply, I rule that Player B gets to Super-Thoughtseize. Player B gets to choose a card from Player A's hand and that card will be shuffled into Player A's unknown part of that players library.

Was I right in my ruling?

This falls under GRV:
If a player forgot to draw cards, discard cards, or return cards from their hand to another zone, that player does so.

Since this was a legal action that was resolved wrong we do not apply the fix described by you.

As Markus discussed the error that was committed was not the drawing of a card, but the failure to discard. This is a GPE-GRV and even has a specific fix prescribed therein. Specifically (slightly paraphrasing from the IPG), if a player was supposed to draw or discard a card and failed to do so, they do so now (at the time the error is discovered).

It looks a lot like DEC because they player has an extra card in their hand, but the reason for why that card is there was known to all players and the actual infraction was failing to discard, not drawing the card.

OK, thanks for the feedback!

Bryan is correct here, but from what you explained, there is actually another infraction that occurred in this situation!

When any player is resolving a spell or ability, all players are responsible to make sure that the ability is resolved correctly. When the player controlling the spell or ability resolves it incorrectly, that usually will fall under a GRV. When the opponent fails to point out when a player's spell or ability has resolved incorrectly and doesn't point it out immediately, that falls under a Failure to Maintain Game State (IPG 2.6).

In this case, since Player A has committed a GRV by not discarding as per the triggered ability, and it was not discovered that they had done so until a turn or two after, Player B has also committed a FtMBS. They receive a warning, and remind them that it is both players responsibility to make sure each spell and ability is resolved correctly.

Hope this helps!

Thanks for the feedback everybody.

I think what fooled me was this in the IPG:
“If a prior Game Rule Violation or Communication Policy Violation directly led to drawing the extra cards, it is treated as Drawing Extra Cards.”

Now I know better, so thanks again for being such Enlightening Tutors! :)
