Pretty cool
If your commander cares about tapping, you probably care about Patriar's Seal which is way more flexible as a colorless card
He would cast Retraction Helix on a creaturesay Rattleclaw Mystictap it to return Briber's Purse to his hand, cast Briber's Purse for zero mana, untap his Mystic with Jeskai Ascendancy, and repeat the process until his Rattleclaw Mystic had +1,000/+1,000 from Jeskai Ascendancy, then attack for the win
Everything you see (card type, creature type, expansion symbol, rules text, power, toughness, and artist credit) are now all overwritten
The best equipment MTG has to offer depends on your decks needs and win condition
