The Sligh deck managed to keep most of its fundamentals in place, although the Mana Curve is now skewed up towards the 3 cc creatures. This is a tradeoff that "The Crew" realized as necessary in the current 5E/post 4th environment. The loss of the Hypnotic Spectre, Swords to Plowshares and Lightning Bolt greatly slowed the environment, with the result being that larger creatures were played (more time=bigger critters). Thirteen critters with a casting cost of 2 or less still keeps the deck reasonable speedy, and the Lancers, Sandstalkers and Fireblast feature good surprise value. The loss of the Lightning Bolt and Mishra's Factory were the hardest  lost cards for the Sligh deck to replace. Two each of Death Sparks and Hammers fill in for the bolts, and 2 Quicksands replace (partially) the lost factories.The biggest change came in the sideboard, where four Manabarbs was no longer standard because of the change in how damage was dealt with under 5th Edition rules (and the implications for COP:Red). Because of this, Nevinyrral's Disks became standard, a trick borrowed from the NecroDeck Because of the decrease in speed for the Sligh deck, and the everpresent threat of Dervishes, Boas, Ghazbans and the blue flyers, Pyrokinesis is added to the sideboard, along with Winter Orbs to punish Blue Base decks (MonoBlue and U/R counterHammer).
