Against Ironcliff the usual responses are Repulsor beast or Thumping wave (grudgingly). In the very late game you can use frenzy combos.
Mirkblood (MKBD) is the card we use to snowball our advantage. In many cases we can grab mana springs on turn 2, which means we can often to stuff like MKBD+ Zyx or MKBD + Young silthar / Shiro/ other 2-drop. In such cases if the opponent cannot clear/dispell MKBD we can get absurd value next turn.
Diretide allows the deck to push face dmg without sacrificing board. It can be situational, but a play like Diretide + Primus on a little fella like Zyx can be a lifesaver in a pinch.
