We must remember that there is more than just selvala in the deck. Mana elves, mana rocks, and draw spells that can help fill in the gaps.
Yes but in each case you have to be net generating mana for this to continue. So even if you draw into draw, you have to have the average mana probably at or under 2 to make this work right reliably. Once you roll up a lot of extra mana / draw it becomes more likely to go on without pause but the first bunch of activations are far more questionable.
This "could" go off, I am just saying its not a guarentee and its still very dependnat on building arround a lot of specific things. When you look at a Mind over Matter combo there is a lot less maybes in it and that is not banned.
EDIT: also, keep in mind that we are talking about a GW combo involving a not very popular commander. I can guarantee that Captain Sisay / Saffi Eriksdotter are more compatative that whan we have been describing not to mention just moving to blue or blue black instead. White Green has what, like one on color tutor for non equipment artifacts. For something to be ban worthy it cant be super niche deck combo.
