You're right, of course, and thank you very much for your input! I am somewhat limited by what I have lying around spare for this little project, so maintaining a relatively balanced level of viability and success is tricky. I don't have as many playsets of appropriate cards as I expected (and I'm definitely not putting 4x [Nettle Sentinel] in!). This is especially visible in the White deck where multiple copies of cards are unfortunately low, but until I get a chance to sniff around my local store's commons box it can't be helped.

I did have reservations about [Elvish Harbinger] and [Sylvan Messenger] in particular, and to an extent, [Elvish Branchbender], and you're definitely correct that they're just not appropriate starting out. Taking into consideration what you've said, I've made the following substitutions:

-2 Elvish Harbinger
+2 Vine Trellis (it was this or Elvish Eulogist. I'm torn between the two, but the word Defender isn't so bad, is it?)

-2 Sylvan Messenger
-2 Elvish Branchbender (the tactic of animating lands requires a bit of forethought and is needless)
+4 Giant Growth

-1 Voice of the Woods
+1 Imperious Perfect

-1 Elvish Promenade (its typing of "Tribal Sorcery - Elf" might be too confusing at first)
+1 Elvish Warrior

Please do let me know if you have any feedback, and thank you very much for your comment ~Ionic
