Kenrith, the Returned King + Smothering Tithe + Anointed Procession + Bard, King of Dale

Kenrith, the Returned King

Smothering Tithe

Anointed Procession

Bard, King of Dale

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 Anointed Procession and Bard.
3. Activate the Treasures by tapping and sacrificing them, adding 3.
4. Repeat.

By activating Kenrith, the Returned King to force an opponent to draw a card, you trigger Smothering Tithe to demand a mana payment. Because your token production is heavily multiplied by the combined replacement effects of both Anointed Procession and Bard, King of Dale, that single missed payment yields an absolute windfall of Treasure tokens. Sacrificing those Treasures easily refunds the mana needed to pay for Kenrith, the Returned King's ability and leaves you with plenty left over.
