1mana monsters

I don't really see why Skeleton shouldn't have 2D sac in its current form. If you're able to sac the skeleton, you end up with a net gain of 3D after playing and saccing the Skull, but it's much more likely that your opponent will attack it before your next sac phase in order to deny you that mana, leaving you with only a net gain of 1D. Being a creature might make it more flexible than an effect, but it's also much more fragile, so the potential mana gain is balanced by the difficulty in actually achieving it.

Also, I'm sorry I wasn't posting about the proposed changes earlier (all of this schoolwork makes it tough to keep up with everything that I want to keep up with), but I'm not happy with the proposed Skyrian Soldier and Mubble.

Giving Spell/Ability Immune to something as small as the Skyrian Soldier seems fairly pointless. How often would your opponent want to waste a removal spell on it anyway? Protection from snipers and the like is also rather silly on something too small to impact the game. How big is it potentially going to be when we change the stats?

As for the Mubble, this change would make Mubble Woods usable as a second Swimsuit, which was the reason for the 50% chance in the current incarnation. Could I get an explanation of why we don't need an "if not a token" clause for this one?

Also, the current Fairy seems pretty weak (it's a Magic Orb that can be easily killed before you get the mana, attached to an attack and life that make it useful for little more than saccing), but stat changes might change that.
