Nylea, God of the Hunt is pretty powerful.
HOW THE DECK WORKS:
-This deck takes advantage of green mana symbols in your permanents.
-Uses fast ramp to get out big, backbreakingly powerful creatures to stomp your opponent.
-"Devotion" uses green mana symbols in the permanents you control to add large amounts of mana to you mana pool.
KEY CARDS:
-Nylea, God of the Hunt is a powerful 6/6 indestructible with the devotion effect. It gives your other creatures trample, making your opponent take large amounts of combat damage.
-Arbor Elf + Utopia Sprawl is a fast mana combo essential in the deck. On turn 2, the combo can produce 4 mana. This makes getting out other bombs very easy.
-Nykthos, Shrine to Nyx also uses the devotion effect, and is the single card that can ramp to ridiculous amounts of mana.
-Craterhoof Behemoth and Genesis Wave alone are potential game-winning cards. They have explosive effects if the deck reaches a large amount of mana.
SIDEBOARD:
-Great Sable Stag is a nightmare for control players. Uncounterable, and adds to your devotion effects.
-Creeping Corrosion completely wrecks affinity, can be played turn 2 with Arbor Elf and Utopia Sprawl.
-Vines of Vastwood protects our creatures from bolts and the norm.
-Scavenging Ooze provides great graveyard hate and an increasing body that gains us life.
-Spellskite unfortunately doesn't add to devotion, but is in to make the game harder for Burn players and Splinter Twin combo players.
-Summoning Trap is a great way to get around permission.
