mtg sanguine bond-blood tribute combo?

Wow, that judge was way off. Nothing about this setup guarantees anything along those lines, except that the target of the original Blood Tribute can still be killed unless enough of the copy Blood Tributes are able to kill the controller of the original first through the "rounding up" clause.

1) The original gets cast.

2) Hive Mind activates, and each other player copies Blood Tribute, choosing their own target. The copies get put on the stack starting from the player to the left (or is it right?) of the active player (in this case, the caster of Blood Tribute, unless they are able to cast it as an Instant) and going around the table.

3) Each one resolves in order. Since they are copies of the original casting, and the kicker was paid on the original, the kicker will occur on all the copies. Sanguine Bond will only trigger on the original casting, since that is the only one that will cause Sanguine Bond's controller to gain life.

4) When the original Blood Tribute resolves, Sanguine Bond will trigger. The controller will still be able to kill the original target of Blood Tribute if they wish, or they could choose another target for it.

And yes, you could use Beacon of Immortality when Sanguine Bond goes on the Stack to save yourself.

I don't know what the Judge is seeing if only those two effect are in play. Both Blood Tribute and Sanguine Bond targets a single player so I don't know why multiple people would die. Unless he was reading Sanguine Bond incorrectly I don't see it.

Sanguine Bond would trigger when Blood Tribute resolves. For example you have 20 health and your opponent has Sanguine Bond in play. Your opponent Play Blood tribute and kicks it. You lose 10 life your opponent would gain 10 life. This would trigger Sanguine Bond which would go on the stack. You then play Beacon of Immortality doubling your life total which is back to 20 Sanguine Bond resolves you lose 10 life. So you would be alive.

EDIT: Sorry I missed Hive Mind. Sanguine bond wouldn't effect his gaining of life from the copy of Blood Tribute

Beacon Of Immortality

ok for Vampires (in case you so go with to bypass with them) i pick to advise here partaking in enjoying cards: Vampire Nighthawk Vampire Nocturnes Gatekeeper of Malikir For the Sphinx deck: Sphinx of the Magosi (attempt to get 4) think approximately Divination you should objective to throw the Vampires in there, i think of of that is a few devastating back up.
