: Deal 1 extra damage this turn.
I'm thinking it's sort of a damaging sandstorm kind of effect.
It could be more damage than that, but let's not go for the 'double damage' thing. That's been done before.
How about:
: Deal 1 damage to target. Repeatable.
Air has quite a few CC-centric cards, so why not make a Rustler-type creature for offense?
and that wouldn't be OP?
Owl's Eye costs 5
to play, has 4 ATK requires 2
for 3 damage.
Dust Moth costs 2
to play, has 1 ATK and requires 6
for 3 damage.
Weapons are slightly less vulnerable than creatures in a shardless meta due to less PC options than CC options.
