This was a missed golden opportunity for a flavour text crossover with South Park. Something like "RABBLE RABBLE RABBLE!" or "Those vampires thinks they can just take our jerbs?!" would have been amazing. Anyway, this card is actually pretty cool. If you're making a drop every turn, it's a free Flame Jet when it enters. In the late game, it's probably going to be more of a Lava Axe or better. Any card that deals damage upon entering is pretty cool, especially those that scale. My only real issue is that it has one toughness, but by the time it matters, it's already done its job. It's not great outside of a Human deck, but then again Wellwisher would suck in a Merfolk deck.
Pros: Damage upon arrival, scales
Cons: Only works in a Human deck, 1 toughness
