This Emerald card allows any character with Shift to be played on it as if this character had any name
For a single white mana, it grants +1/+1 for every enchantment you control and, crucially, First Strike
I really do adore how everythings been implemented, in the same way I loved how Dungeons & Dragons was woven into Adventures in the Forgotten Realms, but I think the power level of the set is a bit mixed when it comes to the new mechanics, despite there being some very powerful cards in Innistrad: Midnight Hunt to flashback and some good creatures and planeswalkers, too
My advice is to have fun with budget options, play other formats, and wait for Shadows Over Innistrad
It wont be returned to the battlefield
