Youll want a wide board to make the most of Raffs ability
For example, while it's in your graveyard, Promise of Aclazotz is a black enchantment card whose mana value is 2
His card comes with massive competitive potential, since the abilities can effectively render your opponents desperate attacks essentially futile
So while you pay a bit more in total to destroy an artifact, you get the flexibility of a 1-drop creature, and the option to cantrip this into ramp
Both cards use moves and abilities that attack your opponent's bench, which can lead to having more than one enemy Pokmon knocked out simultaneously
Artifact tutors arent the most common thing in the world, but this is a great, consistent way to turn meaningless Thopters or Treasure tokens into high-value permanents with no mana value limit
