Nice post, the chicken is an awesome card! 0 mana makes it very versatile for meatshielding. It also has many other uses that I think for forgot to mention.

First of all, it gets 1 attack at level 3 which can actually go quite a long way. It also has enraged with increases its damage and speed when hit. Though enraged may not seem to have any effect, this is a monster in the equalizer ruleset!

In other rulesets I mainly put it in the back, front, or second position to absorb snipe.

The first example of using it is kind of dubious. The fog of war prevents snipe and sneak so in this case, chicken should either be in the second or 3rd position to absorb opportunity.

Great post overall! I really like it. Upvoted!
