Soaring Stoneglider

A 4/3 flier with vigilance on turn three is a rate white does not hand out for free, and this one collects its toll one of two ways. Exile two cards from your graveyard and the flier lands on curve at three, turning the creature into a small piece of incidental graveyard hate pointed at yourself: a cost you underwrite by having a yard worth spending, and one that quietly punishes the mirror-image decks that want their bins intact. Or simply pay the extra and cast it on curve as a five-mana body, a straightforward tax for any shell that never bothers filling its graveyard. The choice is the whole design. It lets a deck that stocks its yard cheaply treat the discount as nearly free while asking a lighter, spell-thin deck to pay up, so the card reads as a bargain to one shell and a fair-priced flier to another. Vigilance is the detail that keeps the aggression sustainable: a body that attacks for four in the air and still guards the ground closes games without committing to a race it might lose on the back swing. The additional-cost framing is old white-weenie discipline dressed in graveyard clothing, charging for reach and evasion in a resource most aggressive decks were happy to spend anyway.
