The main dynamic of this deck is to rush your opponent with a lot of small, crippling threats that can turn into lethat threat at any moment, allowing you to consistently trade up. Then, use your late game burn and air minions to dispatch threats as they come and bring your opponent on deaths door. When this happens, you should be able to hold a minion on at least 1/3 of existing sites. Closing games is really easy if you play your chess game well.
Other interesting elements:
-Tactical Move allows you to reposition your necro toward the center for a more agressive play, making skeletons faster to cross the map.
-Use burrowing and airborn movements as a way to avoir collateral damage from flame wave and poison nova.
-Sturmgeist can be incredibly crippling, as it moves by itself and can shut off spellcasters before they can even cast.
-River of flame and poison nova are hella scary.
Hard matchups:
-Control magic casters: You have to play slower, using burrowing and minion spacing to twart AOE and control. Try to mulligan for Sturmgeists.
-Battlemage: I have no solution for this as of yet. Maybe slotting two sphere of animosity into the deck.
-Other swarming decks: You just gotta be better at it.
Easy matchups:
-Blue goodstuff
-Tall board
-Ramping decks, any decks without good turn 1 to 3.
