Dragon Trainer

Five mana buys a fragile 1/1 stapled to a 4/4 flyer, and the split is deliberately lopsided: nearly every point of value lives on the Dragon while the human that summons it is disposable. That places most of the card's stats in the air the turn it lands, which is the entire purpose of a body whose only text is the token it leaves behind. The design school is old and reliable, the two-permanents-for-one-card approach that runs through countless "creature that brings a friend" commons: divide your investment so a single removal spell cannot strip both halves, and so the flyer outlives whatever the little shell does not. What sharpens the pattern here is how uneven the two bodies are. Because the Dragon carries the whole payload, a sacrifice outlet or a blink effect treats the 1/1 as fuel to spend rather than a permanent to protect; it was never meant to survive. This is straightforward red at common rarity, an evasive threat priced for players who want a flyer topping their curve in a color that has historically had to work to get damage over the ground.
