Blossoming Tortoise + Draconic Destiny + Inkmoth Nexus

Blossoming Tortoise

Draconic Destiny

Inkmoth Nexus

How it works

1. Activate Inkmoth Nexus's second ability by paying 0 due to Blossoming Tortoise, causing Inkmoth Nexus to become a 1/1 Blinkmoth artifact creature until end of turn.
2. Cast Draconic Destiny by paying 1, attaching it to Inkmoth Nexus.
3. Activate Inkmoth Nexus by paying 0 due to Blossoming Tortoise, giving it +1/+0 until end of turn.
4. Repeat step 3.

By leveraging Blossoming Tortoise's passive cost reduction, animating Inkmoth Nexus into a creature becomes completely free. This allows you to pump its power indefinitely using the dragon-granting ability from Draconic Destiny, turning the humble land into a lethal attacker capable of instantly ending the game with poison counters.
