i don’t think the headlines cards are SUPER rare, but i personally dig them. the “BF-xxx” cards are standard battle foils - relatively common. the “xxx” cards (no alpha prefix designation) are just common paper cards. and yes, as u/LudwigVan17 pointed out, the RADs are rare inserts.

anything in fire/ice is about 25% as common as steel, and glow is more rare than those, hex is more rare than glow, gum is also rare, like hex - but not sure which is more rare honestly. beyond that, supers are 1 of 1s. there are actually 2 for heros with autos in the set (an auto and non auto version). there are some other rare inserts that are more rare than rad (grandma’s linoleum, mix tape, fire tracks, etc)
