My attempt at updating my Sidisi Whip deck with Dragons of Tarkir. I will be playing with this deck at FNM and am on a slight budget. I would replace the gainlands with scrylands but would rather now dish out money for lands that will be rotating out.

The sideboard is where I really lack in skill and could use suggestions for a plan.

Sidisi, Undead Vizier gives me a tutor, allowing me to bump a couple cards such as Whip of Erebos, and Assault Formation down to 1 or 2-ofs.

Sultai Charm has alot of value, giving me removal, answers to enchantments like Banishing Light, or ways to get cards such as Hornet Queen to grave so I can whip it back.

Assault Formation really helps out this deck and allows my creatures to do significantly more damage. It helps Courser of Kruphix , Sylvan Caryatid, Sidisi, Undead Vizier, Tasigur, the Golden Fang, and Torrent Elemental .
