Whether its giving a character permanent buffs to health and attack or an ability that triggers when you do certain actions, the effects seem to be very strong
A deck could have as many copies of a card as it wanted
Isnt it great how Oloro, Ageless Ascetic triggers Heliod, Sun-Crowned and Vito, Thorn of the Dusk Rose and Karlov of the Ghost Council with 0 mana invested or ways to interact with this giant soldier short of killing the player
Some include a physical or vocal component, like Blacker Lotus or the Gotcha! mechanic on Touch and Go, some have rules that specifically reference flavor text or artists, like Carnivorous Death-Parrot and Drawn Together, and some require interacting with people or objects outside the game (Ashnod's Coupon being my favorite)
These cards can only be found while drafting Shadows Over Innistrad Remastered but can be crafted at any time to be used in Historic and Historic Brawl formats
That sounds like Id have fun if Im sitting across from an enchantress deck, where usually the only person who has fun when someone brings enchantress is the bringer
