A deck focused on equipment synergies will be the best home for this artifact as cards like Sigarda's Aid and Puresteel Paladin can bypass the inhibiting cost of playing and equipping this card

Stick this in decks that go wide and go tall: Rishkar, Peema Renegade, who distributes counters like Oprah Hamza, Guardian of Arashin, who cares about creature power and discounts spells Selvala, Heart of the Wilds to ramp and draw in glorious green greed Conclave Mentor to bulk up and pad your hand The one-per-turn clause stops the abuse, but it still gives you free cardboard just for doing what Green does best: grow
If a warped spell is countered, it was still considered warped , and it still counts for the purposes of mechanics like void
You can bring this in against decks with one toughness creatures (it can be good both in and against go-wide red), but it should stay away from your deck most of the time
