Similarly, a deck built around very expensive spells (such as Dragons or spells like Exsanguinate with in their mana cost) will likely play powerful, expensive ramp no matter the cost of its commander
Heroic InterventionHeroic Intervention's mana value is two, but casting it on turn two probably doesn't do anything
For just 1 mana, you may get a free swing and treasure token before your opponent has any removal spells or defenders
City of Brass is a decent replacement for Glimmervoid if you cant find any or if you expect to play against a lot of removal and not a lot of aggressive decks, although I wouldnt recommend playing more than two
It's not even that far off from Demonic Bargain, which has you count out 13 cards before searching the library
Stuff like Snuff Out or Dismember are already heavily played cards, but here, you get to draw a card from them because you lost 4 life, and you also get to drain your opponents for 2 life, offsetting your life loss
