It comes mostly in the form of Chocobos, which are generally 2/2 Bird creature tokens with Landfall: This creature gets +1/+0. There are also some great support cards for landfall like Chocobo Kick, Prishe's Wanderings, and Zell Dincht, which can return lands for extra landfall triggers
Thats some serious stonks, and it could end up being a smart long-term pickup
Youre guaranteed to cast a nonland card from your deck and your opponents', and you don't even need to wait to attack
I'd put Etali, Primal Conqueror above the others because its a better card overall
Also, you can equip Krenko with a Thornbite Staff and as long as you have a free sacrifice outlet like Goblin Bombardment you can keep untapping and making more goblins
