Disruptive Stormbrood // Petty Revenge
Outside of mana dorks, Unesh, Criosphinx Sovereign provides a sweet discount to our changelings while drawing tons of cards and Rooftop Storm lets us cast all our changeling for free
I'm also a fan of the Braviary Illustration Rare card that draws from a Van Gogh aesthetic
As far as strategy goes, since Scolipede requires so much energy for both of its moves you'll want to set it up on your bench before you put it into play, you'll want to always use Poison Claws when you get four energy cards on Scolipede, but I guess if you really wanted to you could put this card into any type deck and just use Steamroller but I wouldn't suggest doing that at all
Fun fact: Order of Leitbur was so named because the designers thought it was funny to be able to get an Order of Light Beer. With twelve protection from black two-drops, Chanpheng was well suited for attacking Necro-decks, while Phyrexian War Beast proved surprisingly effective tech for blocking opposing Black Knights
