pokemon card professor sycamore XY Steam Siege 114/114 (Full Art) Base Set Type Pokemon Card Game/[CP4] Premium Champion

Geralf's Masterpiece: is there a combo with Forgotten Creation

Honorable Mention: Heliod, Sun-Crowned - it's the best possible mono-white commander in my opinion, even though it will be obvious that the deck will definitely have the game ending Heliod, Sun-Crowned + Walking Ballista or Heliod, Sun-Crowned + Triskelion combo

You do still have to pay the mana to cast the Vehicle or artifact creature you exile, but since there's no mana needed to be used for Sanwell's effect in the first place, you should have access to however much mana you need

Heartmender: wow, that is one awesome card

The job class equipment does add a creature type when equipped, which is a nice nod
