Honestly, I would start over and try for a card with oath as the leader ability. Way more valuable as most of them are gem draw only while a healer can be obtained through guild shop and other locations.
Plus, alot of people have a healer so friending someone with a healer isn't that big of a challenge. Just my 2 cents.
About the sailor miles, panzer will be gone on the 28th of this month so you better hurry or pray they will cut loose another one.
Also, go back and read the old post in the forum, alot of old knowledge sitting back there collecting dust but some of its valuable ( whats in the guild shop, whats not in the shop, sticky at the top is a great write up).
Sometimes we cry and fight each other but we all love this game and want it to continue and thrive so feel free to ask away, I'm sure someone will help you out if not multiple people.
And watch out for Boop, he's like a 10 year old cat. Pet him correctly and listen to him purr, pet him wrong and he'll scratch your ass!
