Decayed is certainly a drawback, but its so easy to just get four value targets all at once and more than make up for the fact that those creatures cant engage in combat effectively
Not only does that reduce the cost of buying all the cards you need, but a lot of them will already be cards you enjoy playing
This list is very interaction-light and arguably should run Darksteel Forge and Heroic Intervention if it's going to be played in a meta in which Vandalblast and board wipes see a lot of play
Imagine I attack with [c]Calciderm[/c], a shroud creature
These cards have their merits, especially if you prefer a more competitive approach to Commander, but if you find yourself conflicted about including them, its completely justifiable to keep playing what you enjoy instead
But, if you already control Stomping Ground, then you don't need the fixing anymore
