Of these, I think Manifest Destiny, Tax Man, Eminent Domain, and Excise have the best shot at getting a future version printed. White does get to ramp, just very specifically in the way of basic plains. White has always had a taxing and rule making design philosophy, so Treasure or Gold tokens are def good new spaces to give White a ramp option that fits flavorfully. Saying that White does not get to expand it's abilities when Red has already received Impulse effects for card advantage and Black getting to hit enchantments, and Green gets a bit of everything now, is not fair to those players that would like to play White as a main color, not as support or splash. This is just like when Kabira Takedown was printed and everyone was like "Oh no, White can't have that! It's a Red card!!!" when White is in sore need of some payoff for being the best at flooding the board with creatures/tokens. Let White dabble with some color bends, let White get incidental card draw for once instead of gaining life, and let White get either some form of ramp or a fair way to punish ramp decks.
