Pingers Mk. II

Pretty straightforward. Pretty inexpensive, too, since most of the cards are common. Play blue pingers, give 'em poor man's green Curiosity, tap, draw cards, untap, and so forth. I'm still playing around with the different untap spells to see what works best. Does the extra cost on Twitch justify its higher cost over Twiddle? Is the haste effect on Touch of Gaea worth giving up the versatility of Jolt? Is there any way to work Nature's Chosen into everything, without having to add white, or is Instill Energy just better all around? Expect a Mk 3 deck as soon as I figure all this out.
