Arwen, Weaver of Hope Arwen, Weaver of Hope makes it so that each creature you cast comes with an extra +1/+1 counter, and that can get better with typal elf incentives and equipment
At the time, we discussed two possibilities: Wizards reprinting less cards, which seemed unlikely, since reprint sets are low-effort (compared to building an entire new world from the ground up for a Standard set) ways to add money to the bottom line
A base printing is only worth about $1, but the collectable nature of fracturefoils drives this version of The Dominion Bracelet high up
You can do that with one card pretty easily and so for Exploration to be worth it you need to really take advantage of the mana or two you save and the slightly earlier ramp it can bring
Also, Balan, Wandering Knight and Nazahn, Revered Bladesmith seem designed for equipment decks (but different styles from one another)
