jace mtg card Jace, Unraveler of Secrets | Promotional Until your next turn Jace, Memory Adept [Magic 2013]

This slows down protection and takes away one of their strongest abilities, being unblockable

I love this loads

You can even pay a little extra to gain a small creature body on top of the exchange, or some other kind of permanent advantage

I dont see a reprint coming soon so this is a pretty safe pick

So Equilibrium when played correctly is going to slow down your creatures by a turn but at the same time a creature that isnt on the table cant attack you and you can really punish your opponents for cheating in creatures especially if you have a Leyline of Anticipation so I think its a valuable addition to your list
