Dour Port-Mage + Skullwinder + Time Warp

Dour Port-Mage

Skullwinder

Time Warp

How it works

1. Cast Time Warp by paying its mana cost, causing you to take an extra turn after this one.
2. Cast Skullwinder by paying its mana cost.
3. When Skullwinder enters the battlefield, it triggers, returning Time Warp from your graveyard to your hand.
4. Move to your next turn.
5. Activate Dour Port-Mage by paying 1 and tapping it, returning Skullwinder from the battlefield to your hand.
6. Dour Port-Mage triggers, causing you to draw a card.
7. Repeat.

This clever engine sets up an infinite loop of extra turns by constantly recycling Time Warp with Skullwinder's graveyard-recursion ability. While Skullwinder hands a card back to an opponent as part of its entry trigger, you bypass any long-term downside by using Dour Port-Mage's active tap-ability to bounce the snake right back to your hand. Furthermore, every time Dour Port-Mage retrieves Skullwinder, its passive trigger rewards you by drawing a card, turning your setup into an unstoppable loop that secures infinite turns and card advantage.
