Threaten effects have always carried a built-in ceiling problem: you steal something, swing, and hand it back, so the mode rewards you for grabbing the biggest thing on the board even though the card can only pay for so much. This one flips the accounting. The Army it makes is the collateral, and the collateral scales: amass Orcs 2 sets a power threshold, and any nonlegendary creature at or under that number comes over untapped and hastened for the turn. The steal is not a fixed line of text but a function of how big the Army has grown across the game, which means an Orc Army you have been feeding turn after turn keeps widening the pool of what this can reach into. That is the interesting inversion. A conventional temporary-theft spell peaks the moment it resolves; here the same trigger gets stronger the longer the board state accumulates, because the token that would otherwise be a throwaway body is doing double duty as the size gate on the theft. The 1/1 legendary body is deliberately incidental; the card is a token generator whose token quietly authorizes a control-magic effect, and the two halves reinforce each other in a way neither does alone. The nonlegendary clause keeps the theft from reaching the biggest single targets, so the card rewards a deck already invested in Amass rather than one splashing a lone theft effect: the steal is priced against a resource you have to build.
