I have 2 newer players at home, my son + wife. Son started back in February and wife around Easter. Wife has more gems usually because she goes deep in the arena. However neither of them have the grand collection of birds like I do, so they end up spending their silver tickets chasing after remote odds that can land them something nice. They know my tricks but they choose to spend like they have won the lottery. Son even went the stupid way of buying individual silver tickets and ended up with more garbage!!! I already told them they should horde for this week Terence event. I think they each have 1 Terence and 1 Red. Terence is a collector item for old time Angry Birds players like my family, 1 is the maximum you need unless they buff him. Same case for Red. It will be stupid to try to get more Chuck when Chuck is the 3rd bird. As for evo materials, it is always a work-in-progress. I need to leave something undone to give me reasons to play the game regularly. Wife's account have more evo materials because she goes deep in the arena, but she doesn't have the grand collection of birds like me. I play arena to get keys for dungeons, don't care much what rank I end up in. Selling garbage birds help in evo materials and gold coins. It is unlikely the new bird will be so powerful that it has to be used in my main team.
