This has an unintentional infinite combo:

It requires these cards:
- Kodama
- Toggo
- Arid Archway
- Gruul Turf
- Guildless Commons
- Almost any of my landfall cards

The absolutely needed cards are Kodama and Toggo. From there, only 2 of the lands listed are needed. One MUST be in my hand. the other can either be in-hand or on the battlefield. The trigger to start the combo is playing one of the lands. From there, this is the way it plays out:

Land Enters, pull back a basic land. Kodama sees a 0 cost permanent enter. Ignore first trigger.

Toggo sees a land enter and a rock is created.

Kodama sees the (0 cvc) rock enter and you use the ability to play the other land from your hand to the battlefield. It requires you to pull a land back, pull back the first one.

Toggo sees a land enter and a rock is created.

Repeat.

This is nuts with any of the landfall cards. Lotus Cobra = infinite mana. Any of the pingers = game ender.
