so far my counters have been the following: 5 Blitz kills for 1st appearance (5Million HP, 4 kills for 2nd 10M HP, 9 for 3rd, 20M HP, 9 for 4th, 40M HP, 17 for 5th, so I'm seeing a pattern and assume each Ziva in the sequence doubles in HP, I've taken them all out by myself, but it's no longer worth it, you need to use a combination of  A (chaining, (allies make hits same idea as combos in war, must alternate to increase the chain, and B advantage cards, because the 15minute timer you're simply racing against the timer trying to make the required hits before the timer runs out.  Also, a doubling in HP also doubles ziva's attack potential so the number of potential you will need is not doubled, but is probably quadrupled, at least that's approximately what I experienced.
