Eventide is the second set in the Shadowmoor block. Eventide introduces two new mechanics called Retrace and Chroma. Retrace allows one to play a card out of one’s graveyard with the added cost of discarding a land. Chroma makes mana of a certain color a variable that determines the effect of a card.
This card is a modified plague wind in a way, only as an enchantment. Great offensive card for black green. simply enchant a black/green card and attack with that and all other creatures you desire. All the opponents creatures able to block must, and spread the damage to touch all of them with deathtouch, and the're dead(most of the time). Nice to play on a Doomgape or Deity of Scars. It may not allways work if the opponent attacked with alot of their creatures the turn before, but atleast there is a +1/+1 for G + B creatures.
