one piece card game st 08 Deck blue Marco Monkey D. Luffy ST08-001 L

Leylines have become popular sideboard cards for many formats, but why

For a while now, Ive been of a similar opinion to Serge here

It starts off as a 3/2, so when it starts getting counters, it will already have good stats that get progressively better

The downside is that they target once they are dealt damage, which means a Leyline of Sanctity does ruin our plans, but their upside is that they can also pass along damage to creatures, something Stuffy Doll can't do

After all, you get no built-in protection aside from your ultimate, and instead what you're mainly working with is a bit of card draw and ramp

It complements the Necron Dynasties precon perfectly
