Blossoming Tortoise + Draconic Destiny + Blinkmoth Nexus

Blossoming Tortoise

Draconic Destiny

Blinkmoth Nexus

How it works

1. Activate Blinkmoth Nexus's second ability by paying 0 due to Blossoming Tortoise, causing Blinkmoth Nexus to become a 1/1 Blinkmoth artifact creature until end of turn.
2. Cast Draconic Destiny by paying 1, attaching it to Blinkmoth Nexus.
3. Activate Blinkmoth 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 ability, activating Blinkmoth Nexus's animation and pump abilities becomes completely free. Once Draconic Destiny enchants the animated land and grants it a firebreathing-style activation, you can sink infinite mana—or in this case, infinite free activations—into pumping its power to astronomical heights. Furthermore, Blossoming Tortoise's stat-boosting static ability ensures that land creatures you control always pack an extra punch on the board.
