Take control of the board, and dont let go. Even if the deck end up in a board stall, playing "Grinva, Judge of battles" will let your units deal damage unless they are chump blocked. Our Biggest fear is Sandstorm Titan, since it holds all our units to the ground, so you should save finest hour/rapid shot for that guy if you see time sigils played(unless you already have vanquish and/or Valkyrie Enforcer in hand).
The only cards im not too sure of is Inspire and marshall. Other options to include, depending on meta, could be:
Suffocate
Annihilate
Sabotage
Auric Runehammer
Steward of the past
4th Umbren Reaper
Good Luck!
