Feast of Sanity + Lich's Mastery

Feast of Sanity

Lich's Mastery

How it works

1. During your cleanup step, discard to your maximum hand size.
2. Feast of Sanity triggers for each card discarded this way.
3. Resolve the first Feast of Sanity trigger, dealing 1 damage to any target and causing you to gain 1 life.
4. Lich's Mastery triggers, causing you to draw a card.
5. Repeat from step 3 for each remaining Feast of Sanity trigger.
6. Repeat from step 2.

With Lich's Mastery safely in play to protect you from losing the game and to turn every instance of life gain into card draw, you can turn your cleanup step into a catastrophic engine. As you discard down to your maximum hand size, Feast of Sanity intercepts each discarded card to deal damage and gain you life. That life gain instantly triggers Lich's Mastery's replacement effect to draw you right back into the cards you just discarded, fueling an endless loop of drawing, discarding, and dealing damage until your opponents are overwhelmed.
