Considering your deck is set up to generate these each turn, these cards truly do create a ton of tokens
While I do like commanders that dont give away too much, sometimes you just cant help it
I like the flavour of Rukh Egg here, where it's a 0/3 creature that, once destroyed, the egg hatches and a 4/4 flying Rukh comes into play
Three-mana planeswalkers arent supposed to invalidate creatures, artifacts, and win conditions all at once, but Oko didnt get that memo
Further Upgrades The first cards I'd pick up to further juice up the deck would be untapped mana-fixing lands: Watery Grave, Shipwreck Marsh, Underground River, Morphic Pool, Darkslick Shores, Polluted Delta, Sunken Ruins, Undercity Sewers, Urborg, Tomb of Yawgmoth and then maybe a couple more Island / Swamp fetches
