***** Invigorate: Essential for Your Poison Deck

Essential for Your Poison Deck, December 15, 2012 By  Craig Nelson Hamilton "Craig Nelson Hamilton" = Durability:  = Fun:  = Educational:  This review is from: Magic: the Gathering - Invigorate - Mercadian Masques This is a card to deck your opponents with. Jesus Christ! You only need to own a single forest, and you don't even have to tap it. Forget that you give your opponents life. That is meaningless, when they have to take 4 poison counters. If there is any doubt that giving your opponent life in return for dealing poison counters, let me assure you that this life you deal is but mere smite as you flush your opponents down the drain.
