yeah Auto zone and eeveelutions are good against kingdra. Auto zone has to have a descent start.
And eeveelutions is great offense & defense against kingdra, but it needs to be fast.
Eeveelutions is simple, like if your opponent is playing kingdra it would be good to get Glacy x out to stop claydol & zam, leafeon to add energy and attack, jolteon to OHKO
