I don't have statistics, but I am sure this deck has better WRs than the previous deck.

Mulligan:

Except for  the Mana Giant, you can keep elementals in your hand (Imprisoned Phoenix,Sugar Elemental, Violet Spellwing ie). Also try to keep Quest Elemental Allies in your hand.

You have some good combos such as:

• Sorcerer's Apprentice and Chenvaala: After turn 5, if you have 3 or more 1-cost spells in your hand, Chenvaala is in charge.
• Ras Frostwhisper and Imprisoned Phoenix: If you have the coin, on turn 4, otherwise on turn 5, clear the board with 3 spell power with Ras. (Turn 2 play Imprisoned Phoenix, turn 4 play coin + Ras Frostwhisper.)

Your other strengths are Yogg and Mana Giants.

Enjoy!
