might want to add Reflecting Pool instead of the Jungle Shrine also instead of Armada Wurm how about Advent of the Wurm ? Good way to flash in a large blocker you can swing with next turn, i'd also say Balefire Liege is one to look at since he'll interact with allot of cards here

have you considered what would an Earthquake , Damnation or any heavy removal do to your strat ? i would try incorporating an alternative win con in the case someone wouldn't let you play aggro, or at least find out how to protect your strategy (ramp your way to victory so you don't give anybody the time to disrupt your army or mass zombify with something like Creeping Renaissance ) with that said if you still can't win game 1 you shold try solving this issue with some control in sideboard... such as Pithing Needle , Nevermore or making your creatures indestructible.... creativity is the way in mtg IMO

hope this helped :D

Updated again. Went 2-1 in local tournament.
