I'm happy to see Genesis Wave in this deck =D

Me too Caligula! It started with only two; but a third was quickly added :). Wish I had room for four! Just too much card advantage not to use.

Something you probably know, but I just noticed after playtesting this a bit: when you have Trace of Abundance 's shroud it doesn't allow you to abuse the untap abilities of Garruk, Arbor Elf, etc. I understand the need to protect your Nykthos, but the truly insane levels of mana come from these untap abilities. Just something to consider and possibly tweak.

I agree with you completely eeagle....In the last few nights; I've moved it back to the sideboard (and simply added a fourth Garruk Wildspeaker )...I'm not positive that the "extra slot" is going to stay a 4th Garruk, so I didn't want to change it yet; but it does cause a enough problems (as you can't Utopia Sprawl or Abundant Growth the land after a Trace of Abundance either....) to keep it out until match-ups that are heavy land destruction...

I've also toyed around with cards like Privileged Position and Terra Eternal (although starting to call the color on Utopia Sprawl "white" can get a little deep :) to see if I can find other ways to protect the lands...with Rock continuing to grow (which run's 4 Tectonic Edge as well as Control decks often running Tec Edges as well; along with a good amount of side-board Fulminator Mage 's running around...I feel like I need some form of protection for my lands (given the importance they play in the ramping nature of the deck). Privileged Position is the best card; but it just feels too slow in many instances...LD is a tough thing to play against and it seems to becoming more popular in Modern. Fortunately, destroying one land here or there doesn't cripple our deck; but its one of few areas that can slow us down...

I'll change out the main-board one for Garruk Wildspeaker to show what I'm currently testing; and I'll update again once I feel comfortable with the best fit for the "slot" taken. It may very well end up being Garruk; but with 2 Nissa, Worldwaker (which I am liking quite a bit); a full set may not be necessary (although he's very powerful in this deck).....as always, I'd love to hear what you think too! Any great cards you think would be a cool fit?

Thanks so much for the great suggestion eeagle!!
