pokemon e reader card sets E-Reader era Pokémon cards are some of the most unique cards ever printed. These cards were designed to work with the Game Boy Advance E-Reader accessory, letting players scan the to 15+Dimensions POKEMON NINTENDO E-READER 5 CARDS

This combo is meant to be played on multiple turns, as Demonic Pact requires the player who controls it to choose one of four different options, one of which reads "You lose the game." What follows is that players need Harmless Offering to cede control of Demonic Pact, but only after the first three options have been used in order to have the opposing player get the Enchantment with no other option but to lose the game at the start of their turn

These things make it totally fine to play in a deck with no ways to abuse where it is still powerful and versatile

Just make sure that the cards arent too old if you want to use them for official games

It basically says that if I can get this onto the battlefield (and hopefully more than one), and play enough enchantments, I will win
