Of course, we're still waiting to see what "Minor Living Animal Creature" is pictured on both Badger Frenzy and Panther Stealth...
I don't think they are minor creatures pictured. I think panther stealth is giving the elusiveness of cervere to a basic elf type soldier creature. And Badger frenzy is giving you the "crazed" aspect of the honey badger (honey badger don't care). And as someone who is a playtester, I do not recall seeing any badger type creature. But again we've seen hundreds of cards that have yet to see print.
Yes, but the legal targets of those spells are "Minor Living Animal Creature" (Badger Frenzy) and "Minor Living Creature" (Panther Stealth), so the elf type soldier creature should have those subtypes/traits to be a legal target. Likewise, the goblin pictured in the new version of Dissolve must be a Mage, since Dissolve can only target a Mage.
(The original [mwcard=MW1E01] Bear Strength[/mwcard] shows a non-Gorran werewolf (?), which also doesn't exist yet, but it was replaced with a goblin in the 4th printing; likewise, the creature depicted in the old [mwcard=MW1E36] Rhino Hide[/mwcard] doesn't look like anything in the game to date, but it was replaced with a (Timber) Wolf in the 4th printing)
*edit* PS: Silverclaw Ratel is pretty badger-like, and even has a conditional Counterstrike, which makes sense considering what Badger Frenzy does.
