Iridescent Angel

Protection from each color stacked onto one 4/4 body: the angel cannot be targeted, damaged, blocked, or enchanted by anything that carries a color, which walls it off from the entire colored half of the game in a single line. It reads as a five-color hoser despite being a two-color creature. The design is essentially a thought experiment about how much evasion you can pile onto one creature before it stops being interesting to interact with, and the answer the card commits to is "nearly all of it, paid for elsewhere." Two costs keep it honest. First, it is a seven-mana flier, slow even for its era, so the protection arrives long after the games where it mattered most have started slipping away. Second, protection is a defensive keyword: the angel does not protect your board, only itself, so it wins by clawing damage through the air turn after turn while the rest of your half of the table remains fully vulnerable. And the immunity has clean seams. Colorless effects ignore it entirely, which means colorless targeted removal still answers it; edicts that force a sacrifice never target; board wipes that destroy everything do not care what color the angel dodges. What it shrugs off is the colored, targeted, combat-facing part of Magic; what kills it is the part that was built to bypass protection in the first place, which is exactly why a creature this slippery still has to earn the turns it spends attacking.
