Great buys, I like the fallen specter (conbined with the corrupted Pegasus to give it 1 more health or in matches where all health is max) nice to see it jumped in price a lot, didn't realize it was because of the Mimosa (those summoners are too expensive for me :) ) I was also watching it when it was nearly fully printed to get some around 1$ but ended up skipping.

For as far as the chicken goes, I got a bunch of the golden ones stacked up as it's the most essential gold card which will pay back it's price in extra DEC (if you play long enough). I never bothered to level up my regular chickens (I have around 100 of those, most of them leased out to affiliates). I guess the game rule where monsters get more health made it worth getting that one to Level 5 with the enrage ability.

Great post by the way, I might make one with my own buys that worked out great.
