Hi, thanks for the comment, it's easier to discuss things here.
I'll address 1+2 together, cause... I find that with any less pillars it takes too long to get a druid out. The problem with a druid is that it's expensive but has very little hp, so if I have to wait, the opponent can get out an oty, an ulitharid, hell, if I can get it out before they have a chance to play firebolt/ RoF, then next turn I create a mutant that will hopefully survive the onslaught. What i'm saying is from experience I found that 12 pillars works. Maybe 11, I'm not that fixed on the number. This leads into the other point, changing the mark. That might actually be a good idea, and leaf dragons are cheap fodder as well as useful. The problem for me would be : 1)you still gotta make sure they survive 1 turn to use the ability. 2) You're losing light quanta, which are useful for daje vu-ing golden dragons, and I like to keep my options open for the occasional devour/ablaze etc. I find life mark+supernovas to be enough for life quanta.
3) I kinda have to agree here. While a pulv on first/second turn has won me quite a few games, most of the time it's just supplementary. The turtle shield though I find very useful most of the time. Other than crippling most decks, it's good to slow down fed otys so you can get out a druid and mutate them, and basically slow down all kinds of nasty things. I never play it without an explosion on hand though. Someone stealing them would only be rainbow (in which case you're f***ed most of the time, this being the least of your worries) or darkness, both of which, by the way, become easy with a 1st/2nd turn pulv.
4) The druids themselves become fodder once there are more than 2 on the table. With more fodder, you're more likely to get that in your starting hand than druids, which are the essential card. Also, having 1 druid out and lots of fodder (which would happen) isn't very useful, because you can only mutate once a turn.
To wrap it all up, I will try the version without pulv and turtleshield, a bit less pillars and maybe one more microab.
What I'm also thinking is either using werewolves as fodder/attacker (6/6 is not bad) or replacing explosions with steals.
Thanks for the input, and perhaps we should duel sometime to see which deck works better.
