Glad I was able to help you get the Eternity streak going Turin =)
Unfortunately I recently in T50 I haven't been very lucky so I have not been able to expand my collection much. Recently my rare farm deck has had: 2x Eternity (its all I have so I guess you were lucky to win one!), 5x Pulverizer, 6x shard, 17 pillars. Has it worked out pretty well for people? I hope the spins aren't all towers too often. Obviously winning an Eternity is still going to be hard but I would think Pulverizer/Shard wins would be pretty common. I keep hoping to get a 6th Pulverizer to put in, but it seems my luck has run out. I won all 5 Pulverizers in one weekend, I think all from mightyhat's farm, but since then I just get a lot of 2/3 Pulverizer spins and can't get the 6th one.
Sadly I think I forgot to put up the farm deck when I left last night so anyone hoping to farm it will have to wait until late tonight/tomorrow.
