which do you think is better?

i have four samurai (one is lv 70) i dont plan on making a PE emperor, so which do you think is better.
1. Holding on to them until there's an event rare that i would like (wouldend up leveling samurai up out of boredem)
2. trade them off as they are now for resources
3. level them up, make a crappy evolved form then trade it to some sucker

I would for sure avoid 3 because making a crappy evo just ruins the value of the squadmate.
The thing about Event rares is that they will most likely go up in value especially if they are good; the more event rare that are sold, the less there are on the market. Especially since everyone wants to make a Pe version. Take the Ice Golem for example, less than a week ago i bought a few ice golem for 15-20 resource but now they are going for double that. In my opinion, I would much rather keep them. Unless the next Lethal is very good , i would sell for resources to attempt to get the lethal.

This is just my opinion. What I am doing is keeping my sams until i can make them all lvl 70. And by next event if the rare is amazing i will just trade them for the next event rare.
