Okay, Psychic does 14.5 damage per, Zen Headbutt does 14. Barring a crit, Eelektross would still have enough HP to survive this round. But using a combo to bury those hazards means I'm not going to be able to RestTalk my way out of a slight damage race lead (or rather, regain a minuscule amount of footing). Eep.
Super Fang > Rock Slide + Rock Slide {Lightning Dragon's Breakdown Fist!!}* > combo cooldown (Thunder Wave)
*using an enormous amount of rocks to target Eelektross' own side of the field only, in an attempt to bury all the Spikes and Stealth Rocks. Natural consequence may include Eelektross now having the high ground, and Eelektross' half of the field becoming affiliated to Rock-types. Probably won't catch/trap/entomb Deoxys in the burial, but fingers crossed for asking as much as possible.
