The deck is built around Kurumo Bushido allies with Heroic ability. Other cards are there to support these allies in different ways and keep them alive for a little longer to ensure they take down more than one monster. Works pretty good against each lvl 3 Horde. The deck plays very aggressively with high damage potential, has ways to activate Heroic right after playing an ally and to keep him alive afterward, and ovarall tries to take maximum of Heroic ability.
This deck doesn't have many ways to indirectly keep minions under control or rebuilding options (though there're still some cards to help with this), however it doesn't take a lot of careful preparation either (cards are mostly low mana cost). This leads to very dynamic playstyle.
