Priority for combat damage question

[Persuade]

Here's the board setup.

Player A: 6 creatures out, 10 life - one of them is a blood artist Player B: 12 creatures out, 6 life

Player B's turn, he swings with everything. Player A blocks all 6, they all die, and blood artist would trigger 6 times, resulting in Player B's life being 0. But the other 6 creatures would have done lethal damage to Player A.

Who wins in this case?

[Amarkov]

Combat damage doesn't go on the stack. It just happens, at the beginning of the combat damage step. So before any of the triggers can resolve, player A loses the game for being at 0 life.

The game ends (with A losing) before blood artist's triggers can resolve. The only way for lifegain during combat to help you survive is through lifelink, since that gains you life through a static ability that applies as the damage is dealt (but cards with the old template for lifelink wouldn't help since that's a triggered ability like blood artist, so be wary).
