A 2/2 for two is the price of admission in white aggro; double strike for two is not, and that gap is the entire bet this card makes. The metalcraft threshold turns a vanilla body into something that hits for four, which is the math white usually has to pay three or four mana to reach. The friction is the count: three artifacts is a real ask for a white deck that does not want to dilute its curve with equipment and trinkets, so the card lives or dies by whether the rest of the board can keep the condition switched on. When it is on, the upgrade compounds with anything that pumps power, since each extra point of power gets doubled in the combat step. When it is off, you are holding a baseline beater and waiting. That binary is the design's honesty: it does not give you a worse double striker for the trouble, it gives you a normal-rate creature with a switch, and asks you to build the deck that throws the switch.
