Iiinteresting. There's never been a straight-up indestructible creature at common before (I think Darksteel Myr was submitted as a common and promoted to uncommon). Even Fog Bank / Guard Gomazoa are uncommon. I suspect this probably ought to be uncommon too, though 5 mana and not flying mean it might be low enough power level to not warp much.

One of the majors themes of the block and definitely of this set in particular is indestructible. The whole point is to get indestructible creatures down at common, especially given the tools I give each color to cope with its strong presence.

Oh sorry, right, yes. I forgot which set this was in. I remember I did think it look like you'd provided enough ways to deal with it when I looked at this set in the past.
