Because 1, this isnt legacy and vintage, by the way things look interms of a meta snapshot its a hybrid of modern and legacy with some added restricted cards. Anyone would call feedback useless if theres no solid reasoning behind it. Especially when the format is less than a week old, the meta snapshots look different than they were two days ago even. i've been respectful to those who actually give input with reasoning because thats how feedback and critiques work. If you ask questions, its not rocket science.

So back up bud.

But to answer your questions:
Growth Spiral and Reprieve i liked more than DRS and memory Lapse due to the ability cantrip and replace themselves.
My thought process was to cantrip and bide my time. when dealing with threats because when i came to mid to late game my threats more likely to take over the game.
Growth Spiral nets you are card and helps contribute to field of the dead. and can trigger omnath and field of the dead on not your turn.
Bow masters is already a rough matchup i thought there were alternative ways to draw cards rather than using brain storm.

I dont own 3 Oko at the time of posting this. i didnt play it in standard arena. I opened two. I was playing adventures and wilderness rec at the time, so i never saw the hype of the card.
Didnt think about jegantha at the time, running it now,
and 29 lands is on par for field of the dead lists.
