What on earth is the flavour behind this? Is the in-play difference just "on a target creature that isn't this one"?

Also, non flying bird! Noooo!

Trampling non-flying bird, even. I'm going to assume this is an ostrich. I'm pretty sure that if an ostrich wanted to get by me, it would.

Yeah, definitely Ostrich :)

Flightless birds only make sense if it sounds like a flightless bird! I'm going to start calling this the Eberron problem after James Wyatt's comments at pax. You notice how the dinos in Ixalan all sound like earth dinos?

i was sort of making a cycle :P (firesong bird, lovesong dove)

But yeah, i will change this, thanks for the feedback :D

I'm in the camp supporting non-flying birds fwiw.

me too, it allows them to fit better into green, an obvious bird color

1st: Hunting Moa is adorable and flightless birds deserve the love.

2nd: I think "target creature an opponent controls" would be the more likely wording here.

3rd: This is just insane burn. Even without synergy with +1/+1 counters and pump effects and in red, which is the strong burn color. This is twice as efficient as Masticore's damage output.

Yeah, this is :Deal 1 damage, even if you don't stick a sword of kaldra on it...

On the flip side; fighting one creature a turn, while strong, is clearly a thing green can do. This being a one-sided fight is kinda odd though.

since this is too strng, maybe i will revert it to it's earlier state where it fought another creature. i hear this would be preferrable in many ways over the current text

@secret will change wording
