That's a nice card, I didn't even knew it existed!
However, I don't have a go-wide strategy: when I play this deck I usually have 3 or 4 creatures on the board. It would be like
Slagwurm Armor, and that was cut from the deck.
I've not tried
Stoneskin yet, but I think the instant speed makes it an alternate wincon by commander damage. Also I'd prefer
Gauntlets of Light or
Treefolk Umbra to have some redundancy if Doran gets too targeted.
I still get excited when some new card with "+0/+X" comes out. Thanks for the suggestion!
