The Eye is the best card drawing non-Skullclamp colorless artifact in multiplayer
The second one is Burn in the form of Creeping Chill and Conflagrate (assuming you play it)
Fortunately, Rammas Echor, Ancient Shield rewards you for doing so with more cards to trigger it with on future turns
Also, there are situations where you dont want to trigger Prized Amalgam, for instance, you play around Ugin minus ability or vs Anger of the Gods and you have Silversmote Ghoul/another Amalgam triggered to return at your endstep, or fetchland + Bloodghast ready to return your 3/3s on the opponents endstep
Any land that doesnt have this supertype is a nonbasic land, even if it has a basic land type
Placing this in a deck with Gilded Goose, Witch's Oven, and Cauldron Familiar, and you'll have a pretty solid setup
