I'll be honest here...I don't like this card.
It's a great casual card because of all the
crazy things you can odd onto a zero casting
cost flier, but outside of that I don't like it.
And in reality, if it weren't for Affinity based
decks of a few months ago, this card wouldn't
have seen play in major tournaments.
A card that can't stand alone, but does have
some combo value. When you need to get artifacts
into play, this guy is cheap and can serve the
purpose. Pretty worthless in draft and sealed
Constructed - 2
Casual - 2
Limited - 1.5
this was the only 0-cost artifact creature.
That made it the keystone of a lot of combo
decks including the now-legendary group of decks
that made use of Enduring Renewal to create big
loops of death. Other than that, it was
generally just a curiosity. Everyone heard
stories of Ornithopters with huge enchantments
put on them going in for the kill, but it was
mostly just a joke card. When it was reprinted
in Mirrodin block, it suddenly mattered.
Affinity gave 0-cost artifacts a whole new life.
It didn't see much play as there are still
better options, but Ornithopter was seen again.
With the Ninjas of Betrayers of Kamigawa, it got
yet another life as a quick evasion creature.
And last but not least, it was put into 9th
edition with a brand new creature type - Thopter.
Still funny, but not too great.
