Agreed with [MENTION=63]RangerWickett[/MENTION] on this. Cantrips shouldn't be damage leveling pop guns. Spells have an identity and it's world altering effects. Better suggestions would be: Erase, Minor Telekinesis (mage hand), Audible Glamour, Wood Warp, Eldritch Flame (light), Ethereal Seam (mage pocket), and so on. Spells never stop being useful. Hit point damage effects largely do.
Also, if these are going to be At-Will effects than call them what they really are: Abilities. Magical Abilities perhaps, like Dragon's Breath is a magical ability, but not Spells. Spells are arcane completions to prepared rituals for those times when a wizard just happens to bump into Conan. It's far better to keep your roster open for the day, if you're a wizard. But then you leave yourself unprotected against quick incursions.
