Tetzin, Gnome Champion / The Golden-Gear Colossus Tetzin, Gnome Champion helps artifact decks dig deeper by milling three cards whenever a double-faced artifact enters, and it lets you recover one to your hand
You could rework your deck to play better with the emblem, but the artifact-stealing ability is already a good start
That's what makes MTG: Arena so enticing even on free-to-play accountsthe ease with which you can build a lasting collection of fun, powerful cards
(You may cast cards from your graveyard for their escape cost.) If The Master of Keys is no longer on the battlefield when its second ability resolves, you'll still mill twice X cards
Depending on the performance of Zetz and Amegumi, it seems possible for it to cling to the meta, as the share of the virtual enemy Amemai is expected to remain high in CX Set 4
How's that for mana consistency
