Sensei's Divining Top + Starving Revenant + Gwenom, Remorseless

Sensei's Divining Top

Starving Revenant

Gwenom, Remorseless

How it works

1. Activate Sense's Divining Top's second ability by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library from the battlefield.
2. Starving Revenant triggers, causing you to gain 1 life and target opponent to lose 1 life.
3. Cast Sensei's Divining Top from the top of your library by paying 1 life.
4. Repeat.

With Gwenom, Remorseless on the board, you gain the ability to cast spells directly from the top of your library by paying life equal to their mana value rather than their mana cost. This opens the door for Sensei's Divining Top: you can tap the Top to draw a card and place itself back on top of your library, and then cast it right back off the top using Gwenom's life-payment replacement effect. Meanwhile, Starving Revenant bridges the two with its Descend 8 ability, turning every single card draw into a life-drain trigger against your opponent as long as your graveyard is stocked with enough permanent cards.
