I wasn't too sure about putting a Pacifism in Green, but I figured that this would be a good place to have that argument.

Hmm. The wording is very fiddly. I think green Pacifism has been growing in popularity recently (Utopia Vow was in Planar Chaos, but Arachnus Web wasn't, and Lignify played similarly). I like the idea of tying it to Fungusness, and indeed having a common that grants Fungusness to opponents' guys. But this is a lot of hoops to jump through to get what's basically a 4-mana Pacifism.

The funny thing about the fungus ability is that it is very grokkable, but it takes up a lot of words to get it all out there. If we broke the card down into logic chunks it would be

Enchant Creature
Fungus ability
Pacifism for a Fungus

Which is easy enough to parse mentally if this was the last common fungus you saw, but would be rather daunting if this was the first common fungus you saw.

So, I agree, it probably shouldn't stay as is. But I don't think I would be happy seeing this card just keep the "Pacifism for a Fungus" without anything else. Maybe this should come into play and put a +1/+1 counter on the creature... like a dangerous Pacifism for green... and not mention Fungus at all?

Heh. I quite like that idea. That will bring its own set of odd questions - "Why is it putting a +1/+1 counter on the creature if the creature can't use the extra power or toughness?!" - but those are easier to answer both within and outside the set. It works as a green Pacifism (FSVO works), and has nice in-set applications.

Alright, then. Changing over.
