This is a loadout that i use independently of the situation. It mixes good mobility and sustainability and a royal decree, which is i think in everybody's loadout :D. It suits more agressive playstyle of going head on with other champions blasting them to death and leaving. If you are more like a sniper bk player, i would recommend swapping some cards.
