Additionally, you can run other prison effects like Sphere of Safety and Ghostly Prison and cards that reward you for gaining life like Vito, Thorn of the Dusk Rose
We also have several other cards that search your library for artifacts like Tribute Mage, Trinket Mage, and Spellseeker
Last are plenty of creatures that flicker or return other creatures to your hand when they enter the battlefield, which means you can chain some abilities and really get things moving
Paying 2 generic mana to draw one card isnt going to feel amazing, but things very quickly snowball from there
You also get lots of value from creating 4/4s with cards like Elemental Bond and Garruk's Uprising hanging around
While some creatures like Skyclave Apparition and Witch Enchanter can be used as situational removal, the deck has efficient, low-cost non-creature spells like Path to Exile or Abrade to handle early threats
