Reached leegnd for my second time with this list today, has been performing pretty well in rank 3-1. The healing works great against aggro decks with multiple clears. Nether beats mage, and jaraxxus plus rafaam beats most control decks. Hunter is the most difficult matchup.
Always keep twilight drake.
Keep coil, hellfire, sunfury against aggro.
Keep giant/faceless rager against control.
Always keep ooze against rogue.
