Tasseled Dromedary
A one-mana 0/4 is a defensive statement and almost nothing else: it stops the early swings of small aggressive creatures cold and asks for nothing in return, a body built to absorb rather than apply pressure. White has printed this kind of cheap brick before, going back to the Wall of Swords school of defensive creatures, but the dromedary trades evasion and offense entirely for the lowest possible cost on a four-toughness blocker. There is no upside hiding in the rules text, no activated ability, no relevant keyword; the value is the toughness number alone, and whether four is enough to matter depends entirely on what is attacking. The Camel typing is the only flicker of identity here, a creature type that has accumulated a handful of desert-flavored members over the years without ever becoming a tribe worth assembling. This is filler in the honest sense: a curve-filling speed bump designed to give a slower deck a turn-one play that survives contact, nothing it does demands a deckbuilding decision.
