Horn of Valhalla // Ysgard's Call

Most Adventure cards keep their two halves as strangers: a spell you cast now, a permanent you tuck into exile, joined by nothing but the shared card slot. This one wires them into a feedback loop. Ysgard's Call floods the board with X white Soldiers, and those Soldiers are exactly what the Equipment counts, so the sorcery is not merely a token producer; it stocks the board that the Horn scales off when you cast it from exile later. Every creature you control pumps whatever carries the Equipment, Soldiers included, which means the setup half is building its own future payoff rather than sitting inertly the way a graveyard-only recursion card does. The equip cost of three is the tax on turning those bodies into a buff, and that gap matters when the ceiling is a lone attacker suddenly swinging for a whole board's worth of stats. The sequencing runs against the usual Adventure economy: here the expensive half comes first, since Ysgard's Call at lays the groundwork and the cheaper Horn arrives afterward to cash it in. It sits comfortably in white's long habit of turning quantity into quality, but the compression is the clever part: the go-wide plan and the reward that cares about going wide, folded into one card slot instead of two.
