Both have the effect of copying a creature when they enter the battlefield
In the Twin before the ban, both were included, but the number of cards included was more Deceiver Exarch, and in the Twin deck revived after the Twin unban, unlike the above card, which was completely replaced, this card is often used as the main plan
However, Urzas Saga provided its own spin on this rare subgroup of cards with a 0/1 creature that cant be targeted by spells or abilities (from any player, even its owner) due to containing the increasingly hard-to-find shroud keyword
The deck list is: pokemon: 3x Electabuzz 3x Hitmonchan 3x Scyther (Jungle) 1x Chansey Trainers: 4x Bill 4x PlusPower 4x Energy Removal 3x Super Energy Removal 3x Professor Oak 3x Gust of Wind 3x Energy Retrieval 3x Item Finder 2x Scoop Up 2x Computer Search 2x Lass 1x Switch Energy: 8x Fighting Energy 6x Lightning Energy 2x Double Colorless Energy haymaker, a deck that use's weakness and energy removle to win
Comments and suggestions are definitely welcome, as this deck is still a work in progress
