General MulligansWitch apprentice is your actual turn one card, so you may want it early.
Turn 3 you want Feral Spirit or Lighting storm, But the second can be dead on hand vs control matches.
Lesser Spellsstone can be great on hand vs slow decks as it will stack pretty fast.
Doing some theorycrafting with witchwood revealed cards.
The point of this deck is try to perfect curve with a baku odd deck, through playing overload cards. Baku upgraded hero power must be used to summon Wrath of Air totems (+1spell damage) most of the time, synerging with your spell cards. And there are some taunt cards to protect your totems.
Example (A pretty ideal one):
Turn 1: Witch Apprentice (you can get an even cost spell)
Turn 2: Hero Power (WoA Totem)
Turn 3: 3 cost spell (Feral Spirit, Lighting Storm), overload 2.
Turn 4: Hero Power (WoA Totem)
Turn 5: Earth elemental, or Drakkari + Hero Power. Overload 3.
Turn 6: 3 cost Spell.
Context on some cards:
Witch Apprentice -> Has Taunt, can give you an even cost spell
Unstabble Evolution -> Can be played even (any) number of times
Far Sight -> Not sure if i should include or not this cards (thus i just included 1), synergises with 5+ cost cards, turning them even.
Unbound Elemental -> Not sure about this card. Has Overload synergy but likely screw your curve if played on turn 3 (ironically).
Volcano -> Just doesnt fit in this deck, but it is a good card if things get out of control.
Wictchwood Grizzly -> Didnt find better 5 cost minions for this decks, hoping for better WW Shaman cards to be revealed.
Lesser Shappire -> Very unsure about this one (as you can have your board filled with totems). More Overload synergies, and an alternative Win condition. You can play it on earth elemental, Snowfury giant combo or even on Malygos (you know this wont ever happen).
Malygos -> Spell Damage synergy
Snowfury Giant -> Pretty good Overload synergy.
At this point you may be thinking this is some of these decks that seems good on paper but it just doesnt work. Well maybe it is, but there are still some shaman cards to be revealed (stiil not a single overload one), wich could help this deck take form (As it lacks of 5 cost cards).
