Best investment is a gold one. Since we play the chicken so frequently, its an easy 10% boost to DEC winnings. I haven't checked, but I'm assuming the regulars are so cheap because so many people want a gold one instead.
This is great advice. Thanks for sharing. The only time I would consider playing a regular over gold is if I wanted to protect a range/magic monster from a snipe attack. Goes you would never know for us, but it makes sense to have one of each on standby. The DEC bonus makes this the GOLD furious chicken a great card to one. I went to make a purchase after reading your comment.
