Tanuki Transplanter is a card Ive been trying to work into decks, since I really like its triggered ability, so being able to shave three mana off its casting cost makes it much easier to pay its configure cost right away
As an example, where some players see blink & pure combo in Monk Gyatso, I saw Eldrazi, yet critically many of my deep cut decks arise not from peculiar takes on known Commanders, but genuinely unknown or unexplored options
But its not that terrible for black which is used to such indignities
Just paying to respond to a fetch land or Rampant Growth puts you up a card, and you can force the issue with mandatory search effects like Field of Ruin
Common 216 Tinker Bell, Giant Fairy Enchanted The Princess and the Frog 37 Dr
Running commanders that force you to build a deck that is completely unlike anything else is always a fun challenge
