Trinkets is a blue deck focused on using and re-using low cost artifacts for small incremental value. Emry, Lurker of the Loch is the commander, which helps find cheap artifacts with her milling ability and recycles them over and over. The trinkets toolbox has lots of options including card draw (Urza's Bauble, Chromatic Star), mana (Darksteel Citadel, Lotus Petal), graveyard removal (Relic of Progenitus), creature removal (Brittle Effigy) and offensive threats (Chimeric Mass, Bloodforged Battle-Axe). The deck can win by animating troublesome artifacts or overwhelming resource advantage from Sai, Emry and Urza.
