Unfortunately I have been only able to play in mobile and don’t have any stats for this deck. It was able to take me to legend in one day from rank 5 and stay in the top 100 ranks.

Main mulligan guide:

These are the main cards you want to focus at first glance.

Embiggen, Strength in Numbers, Breath of Dreams & Frizz Kindleroost

• If you end up with 2x Embiggen then you should avoid playing both unless you have the coin or ramp. It’s never good if the only play you have is hero power and pass.
• Strength in Numbers is a side quest and should not be kept in pairs.
• Breath of Dreams has the highest win rate in HS replay and for good reason. Since you need a dragon in hand to get its full effect I suggest you keep Evasive Feywing (with or without coin) because it curves nicely. Big Ol’Whelp is only an option if you have the coin. Those are the only dragons I recommend keeping along side Breath of Dreams. If you have the coin against aggro then coining Breath of Dreams in to Scalerider is a great way to get tempo.
• Frizz Kindleroost is pretty straightforward. Play it as early as possible and curves great after Breath of Dreams and even better if you too deck an Emerald Explorer.

Match ups:

Hunter/aggro: Zilliax is a great way to stay alive and stabilize. If I’ve play my opponent already and know that it is not a face hunter then I toss it away for the good cards; since there won’t be too much pressure.

Rogue: Prioritize playing minions that can’t be targeted by spells to make their turns awkward. When playing Emerald Explorer avoid discovering the same minions in your hand to play around Flik. If you force your opponent to play Galakrond for two or less draws then you are doing something right.

Warlock: Swipe and Scalerider (only on coin) are great tools to control the board against Zoolock. Keep a tight board to play around Sea Giant. Don’t overextend verses Galakrond Warlock because plague of flames is a card.

Against the rest of classes I stick to the main mulligan. If anything new comes to mind I’ll update or if anyone has questions towards certain match ups I’ll replay. Thanks and enjoy your big dummies.
