Beacon of Immortality + Leveler + Gwenom, Remorseless

Beacon of Immortality

Leveler

Gwenom, Remorseless

How it works

1. Cast Leveler either from your hand by paying 5 or from the top of your library by paying 5 life.
2. When Leveler enters, it triggers, exiling your library.
3. Cast Beacon of Immortality by paying 5, doubling your life total and shuffling it into your library.
4. Cast Beacon of Immortality from the top of your library by paying 6 life, doubling your life total and shuffling it into your library.
5. Repeat step 4.

This twisted life-pumping loop kicks off by deploying Leveler, whose brutal enter-the-battlefield trigger instantly empties your library entirely. With your library cleared out, Gwenom, Remorseless steps in as the mastermind, granting you the grim privilege to play cards directly from the top of your now-empty library while paying life instead of mana costs. This lets you repeatedly cast Beacon of Immortality for a mere 6 life; because the spell's own resolution shuffles it right back onto that empty library top, you can cast it infinitely, each iteration doubling your life total to comfortably outpace the life you spent casting it.
