The Dragon you fetch up goes into your graveyard, which is great for Bladewing, and while youre only meant to activate this once per turn, you can actually hold priority to do it twice for some fun combos like using Moltensteel Dragon to buff itself up and then becoming Skithiryx to deliver a fatal blow with ease
Would you rather green get another Veil of Summer, or cards like Yedora or Chatterstorm
I love it in ramp to win the game and make your other big stuff trample, madness, discard matters, Golgari self-mill, Jund's Lord Windgrace lands return to the battlefield from the graveyard, Sultai's self-milling Sidisi, Brood Tyrant, blink, midrange, tokens, and loads more
I love playing this one in the early to mid game when Im not in danger of being defeated, and when I feel like a board wipe is going to happen from an opponent anyways
At least Kiki-Jiki is beloved in casual circles and does see occasional Modern play
