A draw-two stapled to a flying body, but the packaging is the whole trick. As a Vehicle, the card resolves as a noncreature artifact: the two cards arrive unconditionally on entry, while the 3/2 flier sits inert and outside the reach of creature-targeted removal until you choose to crew it. That split is the design lever. A five-mana blue spell that draws two and threatens the air would be a fair rate on a creature; hanging it on an artifact frame makes the value trigger automatic and the beater optional, and a crew cost of 3 is low enough that one mid-sized body or a pair of tokens animates it without gutting your board. The trade sits at the seam of blue's usual weaknesses: it shrugs off the wraths that only sweep creatures, since it is not a creature at rest, but it exposes itself to the artifact removal a straightforward draw spell never had to fear. The friction lives in the crew requirement, not the mana. You pay for the flying not at cast but at the point you want to attack, which asks whether the rest of your board can spare the power. And crewing the turn it lands buys nothing on offense: without haste it still cannot attack, so the evasive clock is banked for a later turn while the cards are already in hand.
