Dogwood Elder U Creature – Treefolk Spellshaper : The next time you would draw a card, instead, put the top three cards of your library into your graveyard.

Target creature gets +X/+0 where X is equal to the discarded card's converted mana cost, and has protection from the colors of the discarded card.

When enchanted creature dies, return that card to the battlefield under your control. "You know how it is. Everyday it's 'trade my soul this', and 'give me more power that'. Of course I don't have more time to visit, Mum."	Holy Favor C Enchantment – Aura Enchant Creature Enchanted creature gets +2/+1. At end of turn, return Holy Favor to its owner's hand.

I call on forest's strength – on every thorn on every bramble – for their mass to break our enemies. -from The Fire within All	Plume Serpent C Creature – Serpent When Plume Serpent enters the battlefield, you may search your library for an Island card and put it onto the battlefield tapped under target player's control.
