Valgavoth is never depicted as literally warping the minds of his victims as Emrakul does, so Duskmourns delirium cards are tied to the traps and nightmares Valgavoth uses to torment those surviving in the House
The Graveyard subtheme really does compliment the primary Enchantress game plan and adds some much-needed flavor to the deck
though we dont yet know how many or exactly what cards this will apply to, we do know that the above card, Ravages of War, is one of them
It obviously offers you some nice ramp towards a Planeswalker, but importantly, it gives Commodore Guff a blocker every turn
That said, there might be a situation where youll want to put Furor of the Bitten on an opponents creature and Mires Grasp on one of your own
The purpose of ramp is to let you cast your important spells a turn earlier than normal
