Mulligans
Aggro Mulligans
Kazakus can give such swing turns with turn 5 potion following Kazakus or turn 5 Kazakus + 1mana potion, and should therefor be considered kept in starting hand even vs aggro.
Happy Ghoul, potion of madness and Spirit Lash are very strong keeps.
Radiant is great with PWS, and even potion of madness.
You can sometimes keep Auchenai Soulpriest and Circle of healing for an early clear if you start with them both.
Midrange Mulligans
Mulligan is very similar to aggro, except you can sometimes allow yourself to keep some slower cards depending on matchup.
Control Mulligans
Getting Raza out on turn 5 to start the free heal and later the multiple HPs after Shadowreaper Anduin makes it a worthy keep in opening hand vs slower control decks. Glimmer root and Northshire are good value creation and card draw, which are great for a control vs control opener.
Hilander Dragon Priest gets a lot of extra support with KFT.
Spirit Lash and Happy Ghoul are great early game tools vs aggro.
Cobalt Scalebane and Bone Drake helps with the dragon synergies.
The deck gets a much needed extra board clear with Shadowreaper Anduin, and also can get of a lot of bonus hero powers after both Raza the Chained and Shadowreaper Anduin have been played.
Skulking Geist is ran in this deck, but should probably be cut. It is there to help vs Jade druid and evolve, and to slim the deck for better top decks later on.
Other then that the deck runs its standard backbone strong cards like Drakonid Operative, Primordial Drake, Dragonfire Potion and Kazakus.
Circle of Healing is added for a potential turn 4 board clear with Auchenai Soulpriest or a mass draw with Northshire Cleric.
Shadow Visions should usually be used to fetch another Dragonfire Potion, Shadow Word: Death or pack Elise the Trailblazer. Ysera can be replaced with a Deathwing for yet another board clear, or potentially the non-dragon The Lich King if the card is powerful enough to make up for the lack of dragon tag.
So i prefer Netherspite Historian in Dragon Decks, also i don’t see any Value from Anduin :/
Updated the list now with some changes.
– TSteal
+ Netherspite Historian
– The Lich King
+ Elise the Trailblazer
Anduin is a alternative boardclear with some armor gain, which gives great value if you allready have played raza or from the time you play raza. Deck allready runs dragonfire and holy nova, so a big minion removal should supply extra help vs decks like big ez, jade and so forth.
