Seraphic Steed

Saddle lets a two-drop scale into the late game without carrying extra mana cost, and this Mount pushes that lever about as hard as the mechanic allows. The trigger is not merely tapping or attacking: it is attacking while saddled, which means you have committed four total power of other creatures to the crew before combat, and only ever at the speed of a sorcery. That is a real cost paid in board presence and tempo, and it is what buys the payoff: a 3/3 flier every combat you can afford to fuel it. The body already covers both ends of the racing math, trading up and pressuring with first strike while lifelink stabilizes the totals, so the Angel is upside layered on a creature doing honest work while it waits for the crew. The framing gets interesting in the timing tension it creates: you want those crew creatures alive to defend the Angel they generate, but tapping them to saddle pulls them out of the same combat step and leaves them exposed on the crack-back. Every turn becomes a math problem about whether the token is worth the four power you sink into the ability. This is a payoff engine that rewards a wide board rather than a single threat holding the fort, and the Angel-per-attack ceiling is high enough that even a stalled board keeps tilting value your way.
