Carth the Lion + Liliana Vess + Beacon of Tomorrows + Irenicus's Vile Duplication

Carth the Lion

Liliana Vess

Beacon of Tomorrows

Irenicus's Vile Duplication

How it works

1. Cast Irenicus's Vile Duplication by paying 3, creating a nonlegendary copy of Carth the Lion with flying.
2. Cast Beacon of Tomorrows by paying 6, causing you to take an extra turn after this one and shuffle Beacon of Tomorrows into your library.
3. Activate Liliana Vess's second loyalty ability by removing zero loyalty counters from it, searching your library for Beacon of Tomorrows, then shuffling your library and putting it on top.
4. Move to your next turn, drawing Beacon of Tomorrows during your draw step.
5. Repeat from step 2.

This mesmerizing loop revolves around Irenicus's Vile Duplication cloning Carth the Lion, bypassing the legendary rule and doubling up on Carth's static ability that boosts every planeswalker loyalty activation by an additional [+1]. With that massive discount in place, Liliana Vess's minus ability effectively becomes free to use without draining any loyalty, allowing you to repeatedly search your library for Beacon of Tomorrows. Because Beacon of Tomorrows shuffles itself back into your library after taking an extra turn, Liliana Vess places it right back on top where your draw step can scoop it up again.
