Beacon of Immortality + Vito, Thorn of the Dusk Rose

Overview
If Beacon of Immortality resolves and doubles the life total of the player who controls Vito, that player gains the difference in life (the increase), and Vito’s triggered ability triggers once for that single life-gain event, causing the targeted opponent to lose that much life . If Beacon causes no life gain (for example, doubling a negative life total makes it more negative), Vito will not trigger ; if Beacon is countered or doesn't resolve it is not shuffled but goes to its owner's graveyard [Ruling 2007-07-15].
Step 1
You cast Beacon of Immortality targeting yourself (the player who controls Vito).
Step 2
Beacon resolves and its instruction, “Double target player's life total,” sets your life total to twice its previous value; the difference is applied as life gain or loss as appropriate, adjusting your life total .
Step 3
If your life total increases (for example, 10 -> 20), that increase is a single life-gain event; triggered abilities that care "Whenever you gain life" are treated as "Whenever a source causes [a player] to gain life" and see that single event and will trigger once for that event .
Step 4
Vito’s triggered ability triggers one time for the amount of life you gained and is put on the stack. When that triggered ability resolves, the targeted opponent loses that much life (the same amount you gained).
Step 5
If Beacon makes your life total change in a way that is not a gain (for example, doubling a negative life total makes it more negative), you suffered a life decrease rather than a gain and Vito will not trigger [Ruling 2007-02-01].
Step 6
If Beacon is countered or otherwise doesn’t resolve, it goes to its owner’s graveyard rather than being shuffled into the library and no life change occurs from that spell [Ruling 2007-07-15].
Resolution
When Beacon of Immortality resolves and doubles your life total, you gain life equal to the increase and Vito, Thorn of the Dusk Rose triggers one time for that life gain; the trigger will cause the targeted opponent to lose that much life . If the Beacon causes no life gain (e.g., doubling a negative life total makes it more negative), Vito does not trigger for that event [Ruling 2007-02-01] and if Beacon is countered or doesn’t resolve it goes to the graveyard rather than being shuffled [Ruling 2007-07-15].
