Its worth noting that there are inherent issues with this entire theme, especially an emphasis on finding the most expensive cards, and the gambling-adjacent nature of this whole pursuit
Compared to stronger five-mana red options like Goldspan Dragon (which generates immediate, self-serving Treasure value and is a must-answer threat) or Professional Face-Breaker (which generates repeatable Treasure and impulse draw at a lower cost), Casey & Raph is more political than powerful
The potential to go on a major coin flip streak might seem impressive, but Celebi ex/Serperior is a lot more consistent with its damage output at the cost of less energy
Skullclamp shows up with commanders like Ghave, Guru of Spores, Elenda, the Dusk Rose, Sek'Kuar, Deathkeeper, and just about everything else
As mentioned earlier alongside Enduring Tenacity, Bloodthirsty Conqueror is another take on Exquisite Blood, which pairs best with the Glimmer card (or Sanguine Bond), creating an infinite combo as long as you have a way to gain life to kick things off
