Yup yup. Your lineup was great... and also weird that your opponent went with a level one summoner...
I agree, the Minotaur's stats aren't the most sought after, but in the right rulesets (super sneak being one) he can be pretty awesome. Really, I'm loving the double-strike ability.
I learn a lot in these challenges too! I kind of look for things that aren't as used in hopes to get people trying new things. We never know what awesomeness we'll stumble upon.
