I would deffinitely change the Leader to Hugo or Morphun at later stages.
My problem with tana and Wee Lee, it that you cannot really throw them in for reduction, so basicly they are offensive cards with minimal impact smoothering. And 2 damage reduction in survivor is not much.
So I would also change Wee Lee to stanley, or hiki, because you also need some more damage.
Hobbitusz, you are quite wrong about Wee Lee, have you ever played with him?, that 2 damage reduction is great, why? because in higher survivor levels you get more lives, so that maximizes you damage reduction, for example if you have 15 lives agains 12 lives, you are reducing2 with Wee Lee + the 3 lives diference, so you are creating a life gap of 5.
Plus, this card is not predictable like hiki and even more Stanly ( because of the confidence ), and that is what survivor is about, that the oponent waste pills.
Case 1: i have hiki or Stanly and the oponent has a dmg reductor and a high damage card, i send hiki in the first round ( probably without pillz ) the oponent plays safe and sends the dmg reductor or send the damage card and with low pillz i lose. In the first case i did'n't create a big life gap, in the second casi is the worst.
Case 2: i send Wee Lee with 4 pillz, the oponent sends the dmg reductor ( same result the case before) , but if he sends his dmg card, the are 3 chances: 1 he overpillz and does 4 o 5 dmg - 2 sends with low pillz and loses
As you can see, Wee Lee is more versatile, and not predictable, 1 dmg isn't a big diference in high survivor as dmg reduction
