Sazh's Chocobo picks up counters like a boss, especially with fetch lands involved
It fits naturally in legend-heavy builds and sees play in Murktide, control, and combo decks that value instant-speed answers without sacrificing land slots
Copy all are some strong words to use, and thanks to Modern Horizons 3 you have plenty of inexpensive, non-rare eldrazi that slot in nicely such as Writhing Chrysalis, Glaring Fleshraker, and It That Heralds the End
Each card is double faced, with the ability to transform convert the character from one form to its alt mode
Even more, I do happened to have a healthy number of planeswalkers in the deck, so cheating into play isn't too hard
If the spell leaves the stack, it immediately resumes using its normal characteristics
