in regards to the endless mode question, i think i would depend on my firepower and range, if i had above 7 firepower and 6-8 range i could kill the king from the starting position for a considerable amount of floors [possibly up until floor 30] as for overfeed, its not really a good choice for this challenge, being able to stall whenever is usually a good idea but in this challenge i had no idea when i would need that extra movement from unfaithful steed, i can only say in hindsight having both wand of wings and sacred crown that it might have been better getting over feed [there was no guarantee that i would have gotten those cards ]

man... idk whether my sanity can handle that
