Possibly there will be another way it could happen. For Magic: The Gathering players who joined the game more recently, this post raises more questions than it answers
Thats fine if those cheap versions of characters are decent includes in your deck, but theres a whole list of floodborn characters that simply dont have a cheap enough or effective enough early game play to Shift onto
I already play Gorilla Shaman in some decks to slowly chew through Treasure tokens, but it certainly finds Banana tokens much tastier
Kitsune Mystic / Autumn-Tail, Kitsune Sage Heres another one with an interesting flip condition
The last throwback I want to mention also happens to be the fourth most valuable card (pre-orders) in Tarkir: Dragonstorm
The key tweak is the shift in how energy works: rather than filling your deck with specific energy cards, you simply select the type (or types) of a deck when building it, and energy is automatically generated once per turn for you to attach how you wish (for two-type decks, which are required for the Dragon Pokmon lines such as Dragonites, which type comes up next is randomised, which effectively replicates a multi-type deck equivalent in real life)
