In these decks that have a lot of very-low-investment artifact generation, Oko can function as a supercharged, cheaper Gideon, Ally of Zendikar that gains loyalty to make 3/3s every turn, except the 3/3s can attack right away (because youre using the ability on artifacts that were already on the battlefield) and the Oko gains loyalty and costs less mana
Creature Human Cleric During your turn, your opponents can't cast spells or activate abilities of artifacts, creatures, or enchantments
That kind of cheat-on-attack effect means cards like Colossus Hammer suddenly become a lot more appealing, since you can bypass their huge equip costs and start swinging with massive power right away outside of white colors
