Kenrith, the Returned King + Smothering Tithe + Primal Vigor + Exalted Sunborn

Kenrith, the Returned King

Smothering Tithe

Primal Vigor

Exalted Sunborn

How it works

1. Activate Kenrith's fourth ability by paying 3, causing an opponent who cannot pay for Smothering Tithe's trigger to draw a card.
2. Smothering Tithe triggers, causing you to create four Treasure tokens due to Primal Vigor and Exalted Sunborn.
3. Activate the Treasures by tapping and sacrificing them, adding 3.
4. Repeat.

This clever loop lets you turn the blue activation of Kenrith, the Returned King into an endless stream of card draw for your opponents that handsomely profits you. By forcing an opponent to draw, you trigger Smothering Tithe; thanks to the doubling effects of both Exalted Sunborn and Primal Vigor, each single draw yields four Treasure tokens instead of one. Sacrificing just three of those newly minted Treasures generates more than enough mana to feed Kenrith's ability again, leaving you with a rapidly compounding surplus of artifacts and mana.
