In the case of Innistrad Remastered, the headliner will be a reprint of Edgar Markov, which in and of itself is an expensive card and a good one to pull, sitting at around $70 in value
Free magnetic case, free shipping, printed in the USA
Force of Despair showing Squidward looking sadly out the window may work with the card's name, but has little to do with its mechanic of destroying creatures (unless I missed a particularly violent SpongeBob episode)
I would look to run a mix of hand disruption and countermagic if I had the luxury of black and blue
Based on the latest market prices tracked on TCG Stacked, a foil copy of Eivor, Battle-Ready is worth about $3.93 USD
The real appeal, though, is being able to spend eight mana to potentially end the game as long as you deal damage with the Vorpal Sword to a player
