Hollowhead Sliver + Mind Over Matter + Teferi's Ageless Insight

Hollowhead Sliver

Mind Over Matter

Teferi's Ageless Insight

How it works

1. Activate a Sliver by tapping it and discarding a card, causing you to draw two cards.
2. Activate Mind Over Matter by discarding a card, untapping the Sliver.
3. Repeat.

This loop turns your entire deck into raw fuel by pairing Mind Over Matter with the activated looting ability granted by Hollowhead Sliver. Since Mind Over Matter lets you discard a card to untap the Sliver, you can endlessly cycle through your hand. The secret engine piece that breaks parity here is Teferi's Ageless Insight, which doubles your card draw so that every single rummage yields two cards instead of one, netting you massive card advantage while you churn through the loop.
