Kentaro, the Smiling Cat + Shrieking Drake + Urza's Incubator + Maskwood Nexus

Kentaro, the Smiling Cat

Shrieking Drake

Urza's Incubator

Maskwood Nexus

How it works

1. Cast Shrieking Drake by paying 0.
2. When Shrieking Drake enters the battlefield, it triggers, returning itself from the battlefield to your hand.
3. Repeat.

This clever brew uses Maskwood Nexus to turn your entire deck into a swirling tide of Samurai, allowing Urza's Incubator to slash their mana costs by {2} and setting the stage for Kentaro, the Smiling Cat to let you cast those Samurai spells for zero mana. With your creature spells entirely free, you can drop Shrieking Drake repeatedly, letting its enters-the-battlefield trigger bounce itself back to your hand so you can cast it all over again.
