1mana monsters

Visually, or code-wise for the ability?

I was just thinking that maybe you could try using the ability on facedowns, and if no resolve starts, its not a trap. But thinking about it, I guess that even if it did work, there's not much stopping you from targetting the ability on multiple facedowns to see if they're traps (even if they don't successfully get flipped up). It'd probably be too strong for a 1 mana monster to be able to do that.

Skyrian Soldier - Target effect is flipped face up

(For more than one use, works out more expensive than the likes of Sensor Sweep, and can still be easily killed if the flipping could prove ruinous. Plus, actually resolving and using up mana on non-trap effects is probably weaker than the previous suggestion anyway.)
