Sunmane Pegasus

A flyer that decides how threatening it wants to be each turn, spending to convert from a static evasive body into something you can leave back on defense without giving up the beatdown. The design trick is that vigilance and lifelink land on the same activation: for a single investment it can swing in the air, stay untapped to guard against a counterattack, and pad your life total off the combat damage, all in one turn. That bundling is the point. Most white flyers of this stripe bought raw power in the stats; this one buys keywords instead, so the 2/3 stays a 2/3 while its role shifts turn to turn. The modest body is deliberate, cheap enough to survive the small red burn it will race and just tough enough to trade up in the air, but the two-mana cost keeps the ability a knob rather than a default: activating every turn siphons mana you would rather spend developing, so it earns its keep only in the specific turns where the lifegain or the untapped blocker actually swings the math. It reads as a value creature and plays as a race-stabilizer, the kind of clock that turns an aggressive board into a slow bleed the moment the opponent commits to attacking back.
