This is a swarm deck which combins both Shanna's and Kazar's powers to swarm and buff the board with 1 drops.
Let's go over our core cards:
Kazar- this guy buffs our 1 drop and synergises very well with Zabu, Shanna and Blue Marvel.
Shanna- helps us swarm the board and also helps us reach locations which we can't access.
Zabu- discounts our core cards while also helping us by discounting another 4 drop if we choose to play one.
Blue Marvel- pretty much there for Kazar and Shanna synergy.
Our core strategy is to swarm the board late thus surprising our opponent with a lot of explosive power. Playing around Killmonger should always be a consideration as Killmonger can outright lose us the game, that's the main reason we run Armor.
The best was to build up our power is to use Sunspot to soak if needed then we'll try to swarm the board by turn 6.
Other than the core cards I do reccomend keeping Goose mainly because with him we're less likely to get outscaled by big units and he can protect our ongoing cards from Enchantress. Overall this is a fairly simple deck to play but you do need to be wary of the answers the opponent might have.
