I get the impulsive need to be moving something at all times, whether that be a fidget cube, a stress ball, or just the +1/+1 counters on my Magic: The Gathering cards
Enlightened Tutor became the backbone for many combo-based decks because it could fetch most pieces of combo-based engines, including at various times Aluren, Enduring Renewal, Opalescence, Cadaverous Bloom, Pattern of Rebirth, Icy Manipulator, and Winter Orb
just don't draw yourself to death
Cost reduction in red opens up a lot of combo lines too, plus being an artifact matters for all sorts of red decks
I have my doubts, but the more that Wizards continues to print cheap cards like Metastatic Evangel, the better this white commander gets
You can also shortcut Etratas win condition completely by using the other cards which place hit counters: Ravenloft Adventurer and Mari, the Killing Quill
