Karn Liberated If youve ever touched a Modern deck, you know the horror of a turn-3 Karn Liberated exiling your lands so you cant play the game
It has Ninjutsu for four mana, and when creatures you control hit a player, you make a Treasure and manifest the top card of that players library
Unearth is a returning mechanic that lets some permanent cards return to the battlefield one last time
It is hard to know how important it is to keep your land count up compared to the spell you are considering countering
As we've seen, black and white have plenty of options to remove any type of permanent, but if you lean strongly into blue and enemy creatures give you a headache, you may be better served with either temporary removal (bouncing) or doing what blue does best: Use counterspells to handle cards before they become threats
Again I wouldnt put too much credence into the prices provided as theyre most likely out of date, but the book will give you a roundabout value for most cards in sets made prior to 2018
