However, perhaps this card, despite being an Aura, was quite playable in Standard at one point. There was a time where the only non-damage based removal in Standard was Doom Blade (in M14 as an uncommon) and Dreadbore, plus Murder and Grisly Spectacle, neither of which were really ever really played in Constructed. Abrupt Decay could work (because the land itself has a CMC of 0) and Smite (which some White decks did sideboard at one time). Still, oftentimes, I saw your opponent often just taking the 7, or having to chump block, or expending some combat trick. As it turned out, though, no one decided Awaken the Ancient was really worth it.
Awaken the Ancient may have been at least a fringe Constructed-playable card when the meta wasn’t heavy on answers for it. I still think there’s value in this card, and as Red usually doesn’t invest highly on the higher-end of the mana curve. If you can get in for 7 for only 4 mana, the potential cost of a losing a Mountain is minimal. Played correctly, it can be a huge blow for an efficient price. Unfortunately, it looks that it will ever only truly find a home in some strange Commander brew. Being the Timmy I am (one who likes to win with big crazy spells like this), I just have always wanted to see this card help someone win out of nowhere. I’m still dreaming. In any case, I still love the concept.
