Players can see the locations of monsters that Special Summon themselves from the deck

Yes, but by this point, the player has already committed to applying the effect. You can’t back out of this screen without adding one of these “Drytron” cards to your hand.

In my situation above, you can see the position of a Nefarious Archfield of Nefariousness (or any other card that you can currently Summon from the deck), and then close out of the deck without doing anything.

I’m not sure if you sent this before or after our conversation on Discord. If before, then disregard this.
