@ ICB: Thanks for the input, but so far it's working for me, and after some adjustments it's sped up noticeably, I think. So, I'll stick with it anyway.
@ Kurohami: Interesting idea, I wonder if there's a way to exploit that for a deck. Too bad there's no Nightfall equivalent for Light creatures.
For the sake of argument, I can't provide statistics or claims on the performance or potential of this deck. I can only offer my opinion based on casual observation through casual gameplay. I don't grind, and I certainly don't take notes on how many turns it takes to win, how many times out of so many games it wins, and so on. Not that I have a problem with those that do, it's just not my schtick.
If someone wants to find out just how my version stacks up, feel free. I'm certainly curious, just not curious enough to play in a scientific way at the expense of my fun.
Speaking of which, it's been modified...
x12 Emerald Pillar
x3 Emerald Dragon
x4 Horned Frog
x6 Heal
x1 Druidic Staff
x4 Forest Scorpion
My only problem seems to be a consistent shortage of pillars, though I haven't noticed a drastic effect on performance. I may very well take ICB's advice and ditch the dragons just to free up more space for extra pillars. I usually don't bring out the dragons til the kill-turn anyway, so I always have enough for them, but I always seem to be short on pillars early on. Ah well, something to consider.
