Ok, here is my workaround (if that is what it truly is, i doubt i have created a fully functional rules correct card on my first try)
A few problems i think may be there: Since I don't think the untap ability has been coded to not allow untapping during summoning sickness, so it will most likely allow to untap during sickness. Idk if I did it right, so it may allow to untap whilst untapped. (not knowing if i did it right meaning I didn't know how to put in conditions, and am seriously hoping that its already hard-coded in.) I'm also going to test it, but I'd like some more opinions

EDIT: ummm... i've made a few goof-off cards before, and somehow gotten them into the game, but I do not remember how I did it, and I cannot seem to get this one to show up. How do i do this?
