And King Shield means shit against a staller, plus Umbreon shrugs off Shadow Ball even after Weakness Policy easily. Though the battle could still be turned against you - because youre faster (outside of curse and/or -speed natures), you cant kill WP Aegislash without dying first unless it stays in Sword Form
