So, we were given this preview on the Blood Brothers and Mobage Facebook page...
Well, turns out DeNA isn't too smart, because they've already added this familiar to the Bazaar roster.
The new familiar is Lanvall, Lizard Knight, with the not-so-new ability Rush.
Unlike most mounted familiars, this guy doesn't have two skills either.
Who knows whether or not he'll be able to attack twice despite lacking a second ability.
On the other hand, the stats will almost surely be past 10k each when evolved properly.
Though it will be a good familiar when fully evolved and maxed, it's a bit disappointing that we aren't seeing a new skill. Oh well, there's always next time.
