It all depends on how you want to make of the ability, either you want to deal as much damage as you can before you switch out, or if want to stay above that 50% hp for as long as you can, if you want to quickly sweep and switch out, go with the aqua jet and sucker punch set(with life orb,OBVIOUSLY)why aqua jet over liquidation? Because of priority,
Ike, if this thing went up against a mega-blaziken with brave bird, would you like to move first or last? Your choice completely, but most like you are going to get fainted by that godly speed and super effective damage, even if aqua jet does not have enough power to faint it, it will at least make it so that the next Pokémon will have an easy kill. The rest is pretty simple so I am not going to explain. If you want to go with a bulky set, leech life will keep you alive. Assault vest and iron defense with it’s already superior defensive stats make it technically invincible, the only downside it that you can only sweep with liquidation(and First impression for the first turn. Hope I helped?
