Hi judge!
Can you elaborate on the step-by-step of resolving Tempt with Discovery? When do opponents choose if they are tempted? Do they know if other opponents are tempted? Do they know what land you grabbed, or what lands other opponents grabbed? When you search for the additional lands, do you know what lands your opponents searched for?
Thanks!
This is a spell that almost no one resolves correctly, but to be fair its resolution has a lot of steps:
You search your library for a land and put it onto the battlefield.
Starting with the player whose turn it is and going in turn order, each opponent chooses whether or not they're going to search for a land card. The search doesn't happen until everyone has chosen.
Every opponent who chose to search for a land does so simultaneously and puts it onto the battlefield. Players should set their chosen card aside face down and only reveal it when everyone had made their choice.
For each opponent who chose to search for a land, you search for a land and put those lands onto the battlefield. Technically these are multiple, sequential searches but that only matters for cards like Aven Mindcensor.
Each library that was searched gets shuffled by the player who searched it. This is usually the owner, but sometimes isn't when cards like Opposition Agent get involved.
So... who knows what when?
All opponents know the first land you searched for before they choose whether or not to search for a land.
The choice to search or not is made sequentially, so your opponents will know if previous opponents were tempted or not.
Your opponents don't get to see what lands the others are searching for, though they can, of course, communicate with each other and make their intentions known.
You know what lands your opponents have searched for before you search for your additional lands.
