I think Supply Runner is especially incredible, as it allows you to have Swiftness already in Silver and all that for just a few bucks! As for the others, I don't even hope to be able to achieve a high enough level for my decks to be able to enjoy the Swiftness bonus from them. Great post, as all of them in this series!

I also started liking the supply runner a lot recntlky because of it's high range attack with swift + strengthen ability combo which is very beneficial in medium to high mana matches. Thanks for vising me and the awesome support my friend. :)
