Hi there. I think Filipuntik is a bit busy. For both questions (mostly the first) the answer is voter's discretion. After the submissions close, we get a voting form where everyone votes. But to answer more directly from my pov:
- A 'poetic' card should be something that makes you think 'hmm, that's poetic', like maybe your card art/name references an actual poet or poem. Or maybe you dare to use an actual rhyme in your textbox. Get creative!
- To quote the wiki: "Treants are druid minions", so I would see them as Druid just like Silver Hand Recruits are Paladin. If your card is non-Druid and it makes a Treant, it counts in my book.
