The lotto is extremely streaky. i usually do pulls-when i used to do lotto early on at 11 at a time. i am not sure if this reduces the streakiness or not.
Another way but quite time consuming would be to wait and time out the lucky iczer of the day page. If you keep tabing back to it then see a 5 star pop up you like then you can go and lotto alot in hopes that the 5 star will repeat. i haven't tested this out though.
I have 150 usd in gran still residing in my account. I hope that the EX 12 will be less than 250 gran a card but if it is not then i think a full box goes for like 45 usd. the other 100 usd i usually spend on 3x gold box for set 12. If I spent the entire 100 usd on lotto pulls Friday and recorded the results I have a hunch that i won't come up with what I need to feel satisfied based on what I would need to recycle. Even at 5 stars i am recycling at a rate of 60% meaning for every 10 i get i have to (on odds) recycle 6 of them since I will be over 3.
I am really looking forward to set 12 though -7 Duchy units! So i want to use my funds there.
If the lotto looks good on friday based off user pulls/results I will try to keep an ongoing stats thing going. if the recycle rate looks good I might go in-i am looking for 85% or so.
new users with out many cards and looking to spend i think ex lotto is the way to go and then hyper.
Nought's had, all's spent, Where our desire is got without content;'Tis safer to be that which we destroy Than by destruction dwell in doubtful joy.
