Mulligans
General Mulligans
Since this is a late game focused deck, you want as much early presence as possible in your starting hand.
The more spells you play, the cheaper Shirvallah gets and the more Lynessa gets buffed. Keep getting more value from those cards in addition to Galvadon with Zola and two Faceless Manipulators. Use Zihi to restet both players to 5 mana crystals to make your big minions even harder to deal with.
