Atog: I tried PMing you this, but I guess open discussion is best discussion.

Actually, I have Viridian Shaman's sideboarded in for artifact destruction just in case I do come against a Plat angel, I do run all three cards for various win conditions, so in case I have to grape shot a plat angel, then roll out with a few more spells for a brain freeze/tendrils. The card shop that I play at tends to run rather creature heavy with a few exceptions, but I really had no problems pulling of a double brain freeze for 27 and 30 by turn 5 at the latest or a tenrils for 20 earlier than that. I was using lanowar elves along side elves of deep shadow just in case I couldn't pull a birchwood for black mana. Once again, I'm not sure if these are high calibur ideas still, but they seemed to work pretty solid for me. Oh, also land grants were damn fantastic cards for getting my nettles to untap for free at that and bring a land into play in case I hadn't played one that turn.

oh and I keep Mercy Killings in the deck in case of indestructables. green spell for my nettles and it makes the player sacrifice the creature, sure they get a butt load out of the D.C. but strangely I'm comfortable with that.

edit: I also dropped a regal force for like 21 cards. I, uh, forgot about a good deal of my tokens, that was rather amateurish of me. >_>

I actually run something like this, but I run brain freezes and tendrils of agony in addition to the grapeshot for other types of win conditions. In the local tourney I play in usually, I managed to use all of my various win conditions as well.  I'm also using Elvish Prominades as well for additional mana sources. I'm also considering dropping a city of solitude to make my turns safer. Not sure if these are good ideas or not, but overall I'm pleased with how this deck is running.
