While putting cards in the Lost Zone literally means sacrificing cards that you will never use again in a match, some Pokmon cards can benefit from it, like this Cramorant that can attack for free as long as you have four or more cards in the Lost Zone: Another example of Lost Zone-hungry cards is this Giratina VSTAR that one-shots anyone with its VSTAR Power, Star Requiem: Will the Lost Zone be in Standard
A staple of 5-color domain decks, Leyline Binding is one of the best and cheapest versions of this effect, and as such, its seen play in many formats
While March of the Multitudes will be a format defining card right away in Standard, its still a multi-colored card that doesnt have as much upside throughout its Standard life as the top three cards on the list
It also costs a lot of mana upfront, which keeps it from being the best of the best though I love pairing it with Vilis, Broker of Blood
Its also nice to see the man himself in the frame without his flunkies, and this one will set you back around $18
