I think skylasher is way more viable than people think. 2 power + reach is very good, and he beats counterwars. He may only be a sideboard option against delver but that deck has the potential to hit that type of status and relevance and this keeps it in check. Also just good in a Jace war.
Also does anyone see anything to armed // dangerous? If only for Armed? It seems rather cheap to make something that lethal. I can easily imagine you one shotting something with a 5-6 power goyf very out of nowhere, especially with exalted triggers. Maybe its too narrow but its just such a strong pump.
There are already either cheaper way to give double strike, or ways to do it in Instant, which seems much better than the +1+1 in most decks, none of those cards ever say play.
