Your worrying since Lola has no attack nor power manipulation abilities as assurance for her in certain rounds.
The thing is.. Lola is a very good card. She is worth her price unless a good 3 star from berzerk came up.
You play her as it is... either make the opponent pill against her since she could output up to 8damage.
Or use her as a block. Which looks like a -3 damage min. 0.. except that she cannot save you in KO situations.
Still, she has a very great synergy with other berzerk. pramis
Lola is weakest of course in playing against SOA deck. maybe among the Berzerk clan. She's the one who has the greatest disadvantage against SOA's...
Yeah, in most cases shes better then a Dr (especially in elo when many 2 stars have 1 or 2 damage)
But their are exceptions, like tesg said, against + life per damage cards and in KO situations. But still an extremely good card. Also, now with rudy out there u can use him if you dont have quite enough to get lola. (as he is quite similar)
