Liliana's Mastery was center stage for the Top 8 of Pro Tour Amonkhet How many copies of Liliana's Mastery are you supposed to play?

This is an interesting question to be sure!

Pro Tour Amonkhet winner Gerry Thompson (shout out to @g3rryt) played three copies in his mono-black Zombies deck.

You can certainly defend the Mastery as a three-of ("If Gerry did it, it was right." -Patrick), but there are some pros and cons to this decision. The Zombies archetype would certainly play fewer than twenty-four lands if it didn't have a five drop at the top of the curve... Does it make sense, ultimately, to cut a copy?

How about two?

First-time Top 8 competitor (and onetime Top 8 Magic Mockvitational winner) Christian Calcano (shout out to @CCalcano) cut another! Christian's deck was very similar to Gerry's, just trading one Liliana's Mastery for an additional fast removal spell.

On the other hand, the black-white version played all four copies (at the cost of a couple of two drops).

So what is the right number?

If you think Zombies is the ascendent archetype (it did just win the PT) you may want to play all four copies. To be fair, even two-of Calcano ran the other two Liliana's Masteries in his sideboard.

Liliana's Mastery is an Asymmetrical Crusade

It's not just a Crusade, it's a Grizzly Fate. It's a giant, spread across multiple bodies.

For five mana, you get two 2/2 Zombies... But they are automatically 3/3 by default due to the enchantment itself. It's cool, especially in a mirror, to make all your Zombies bigger, but that's not all.

At the point that you are hitting five drops, you really just want to draw more and more of this thing. You get card advantage two-for-one and all your Zombies get bigger and bigger, snowballing the advantage.

Liliana's Mastery Killed Verdurous Gearhulk

Poor Verdurus Gearhulk.

Not long ago it was the huge five-drop of choice, kicking Ishkanah out of B/G top ends. It could be a big body itself, or it could spread value across multiple bodies. Especially with Winding Constrictor, Verdurous Gearhulk could create an immediate and compelling swing.

Liliana's Mastery just does the same thing, better.

Same cost, similar impact.

Except when it isn't.

The Gearhulk is 8/8 on the low end whereas the Mastery is "only" 6/6... But the Mastery is across two different bodies. It can also potentially spread even more damage, depending on how many Zombies you already have.

And if you are B/W?

It is great with both Binding Mummy and Wayward Servant, creating multiple triggers even as it buffs the two-drop.
