Has there been an "X 1/1" spell before? I thought there was, but I couldn't only find similar spells such as Martial Coup. It makes me think X chump blockers might be too good in limited, but I don't think they should be.
Should it cost more/less? Be an instant? It's a bit boring for most turns; maybe it would be better to simply make it N for CMC N for a value not used before?
Either way it seems obvious for Elspeth, even if it's a reprint. Useful but not that strong, but a lot better with a white planeswalker around. Especially since white is taking over from green in "X 1/1 creatures".
But the most direct comparison; Martial Coup costs it at with an optional Wrath.
Snake Basket is , kinda. +turn kinda. And Warbreak Trumpeter is just ODD. Kinda sorta but you get a free 2/2 or 1/1 out of it and it's kinda instant speed and kinda not.
Verdeloth the Ancient gives you it, but as a tack on to something else that directly interacts with them - and charges you accordingly.

Martial Coup and Alliance of Arms are what spring to mind, but Vitenka's right that Goblin Offensive is a more direct comparison.
Given Martial Coup, I guess this is probably appropriately costed?
Well, given that, at the time Goblin Offensive was first printed, Shivan Dragon was considered above the curve, yeah, this looks about right.
Decree of Justice also gives you a card, though.
I wouldn't worry too much about the card's CMC for Limited as much as the fact that it's easily splashable.
