Filigree Sages

The whole pitch lives in the gap between what the ability costs and what it can untap. Pay two and a blue to untap any artifact, and most of the time the math runs backward: you spend three to free up something cheaper. The card only earns its keep when the target it untaps produces more than three mana, or generates a counter, a card, or a token worth more than the activation. That makes it a combo enabler by construction, a creature whose body is almost beside the point and whose worth is entirely a function of what other artifact is sitting next to it on the battlefield. The Vedalken Wizard frame is fitting: this is a piece of machinery designed to spin a loop, not to trade in combat. Pair it with an artifact that taps for three or more mana including a blue, or any artifact whose tapped ability is the engine you want to fire repeatedly, and the 2/3 stops being a 2/3 and becomes the off-switch on a faucet you can open again and again. Standing alone it does nothing a player wants; the activation is too expensive to be a tempo play and the body too small to matter. It is a key, and the value of a key is set entirely by the lock it opens.
