The first thing to consider is do you need any attackers or defenders?
Secondly, do you have candies?
If the answer to the first question is 'no, not really', then I would save everything in anticipation of a rework.
If it is yes to defenders...then Snorlax - if you have the candy.
If you need attackers, then I would ask what are you short of...and I would lean towards the Es/SoB egg.
...but mainly, what exactly are you lacking?
Personally, I would hold off until we see a rework.
