mtg slime commander deck Deep Dive: Slimefoot And Squee MKM] Slime Against Humanity :

It starts tiny, pairs poorly with fliers, and trades down with all sorts of fodder creatures

Sphinx of the Steel Wind Sphinx of the Steel Wind falls in the keyword soup category of cards

Let me know which it might be, if you so choose
