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
Theres also a few triggered abilities that further double-counters, like Byrke, Long Ear of the Law and Fractal Harness
The most logical next step would be a set focusing on Generation 2, with the featured Pokmon potentially being Tyranitar, Umbreon, or even one of the Legendary Beasts like Suicune
While it may not discard two cards, it is one cost cheaper, inkable, and handily has four will power, making him less susceptible to be wiped out by Steel songs
