Henry Wu, InGen Geneticist + Chatterfang, Squirrel General + Nadir Kraken + Artificial Evolution + Druid's Familiar

Henry Wu, InGen Geneticist

Chatterfang, Squirrel General

Nadir Kraken

Artificial Evolution

Druid's Familiar

How it works

1. Cast Henry Wu by paying .
2. When Henry Wu enters the battlefield, its exploit ability and Druid's Familiar's soulbond ability triggers.
3. Holding priority, cast Artificial Evolution by paying , changing all instances of "Human" on Henry Wu to "Squirrel".
4. Resolve the Druid's Familiar trigger, doing nothing.
5. Resolve the Henry Wu trigger, causing you to sacrifice another non-Squirrel creature with power 3 or greater.
6. Henry Wu's second ability triggers, causing you to draw a card and create a 1/1 Squirrel creature token and a Treasure artifact token.
7. The Squirrel's exploit ability, Druid's Familiar's soulbond ability, and Nadir Kraken trigger.
8. Resolve the Druid's Familiar trigger, doing nothing.
9. Activate the Treasure by tapping and sacrificing it, adding 1.
10. Resolve the Nadir Kraken trigger, causing you to pay 1 to put a +1/+1 counter on it and create a 1/1 Tentacle creature token.
11. When the Tentacle enters the battlefield, Druid's Familiar's soulbond ability triggers, pairing it and the Tentacle.
12. Resolve the Squirrel trigger from step 7, causing you to sacrifice the Tentacle.
13. Repeat from step 6.

This ingenious loop transforms Henry Wu, InGen Geneticist into a relentless sacrifice engine by using Artificial Evolution to rewrite his genetic code from "Human" to "Squirrel." Once modified, Henry Wu grants himself and your other Squirrels exploit, so that when a creature is sacrificed, Chatterfang, Squirrel General's replacement effect doubles your token generation while fueling your death triggers. Every time you draw a card from the resulting exploit, Nadir Kraken leaps into action by letting you pay for its triggered ability using mana from the Treasure tokens Henry Wu creates. Finally, Druid's Familiar anchors the sequence by continuously soulbonding to new tokens as they enter, providing a steady stream of eligible sacrifices to keep the engine spinning indefinitely.
