darksteel cards mtg Forge - Darksteel - English Darksteel Colossus is indestructible Custom Card a Day 109:

The control-change effect of Emrakul's first ability lasts indefinitely

It can apply a tremendous amount of pressure because as your opponents health drops below half of their starting life total, Anya gets a +3/+3 bonus and becomes indestructible

Your commander costs 2-3

Note that this is a little different than the Near-Mint/Slightly-Played/Heavily-Played paradigm used by retailers selling Magic cards

It can be in your assassin-themed deck, but it sees its fair share of play in Edgar Markov decks too

Im going to begin by trying to figure out if selling it is even correct at all, then well assume its time to sell (whether it is or not) and see how those two scenarios may play out.
