Do you check for
KO as soon as you calculate damage or is it at the end of the attack phase? Is there a specific order for extra damage calculation outside the normal attack? This matters because of Reckless Charge potentially KOing both attacker and defender simultaneously. It also matters because of
Electrified Spikes.
[Source: WotC] 
We are constantly checking for
KO. In the case of
Electrified Spikes, it will deal the damage to the attacker before combat damage is assigned. If the attacker is Ransack in bot-mode, he will benefit from the additional damage and increase his attack by 1.
