Mulligans
General Mulligans
These are generally the best cards to start with. Your other combo pieces apart from backstab (Mecha'thun, Anka) can be easily gathered by using Gral, Countess Ashmore and Jepetto Joybuzz.
Step 1. Make sure you have Anka, Mecha’thun and backstab in your hand
Step 2. Empty your deck by using Myra’s unstable element or by drawing like normal
Step 3. Play Anka.
Step 4. Empty your hand apart from Mecha’thun and backstab.
Step 5. Play Mecha’thun and backstab him. Mecha’thun will be a 1 mana 1/1 and backstab will efficiently kill him, killing your opponent.
