Control druids are the hardest matchup, other ones are manageable. Swapped 1 Explosive Rune and Ice Block for 2x Netherwind Portal for the last few games. Netherwind Portal is good vs decks with little to no minions (Druids with Oaken Summons and Big Priest mainly) but it needs more testing. I used Ice Block only so I had a secret all the time to trigger cards that require a secret.
