Dr. Who
Sergeant John Benton could have some potential. He's a potent attacker that draws you cards. Yes, your opponents get to draw cards, too, but when they do, they won't block him, right? Yeah... thought so. Pass, except for more group huggish or more aggressive approaches.
Everybody Lives! is an intersting take on Teferi's Protection. It's a way to stop a combo win, so that's an additional benefit. It does not protect your non-creatures though. It protects your opponents boards, too, so it does not help with profitable blocks like Heroic Intervention. Angel's Grace is another card in that niche. I would probably play it instead of Intervention. There aren't many ways to interact with game-winning combos in WG. I will test it, if I can trade for one.
Everything Comes to Dust could be an option for Elfball, but is probably too expensive.
Lord of the Rings - Holiday Showcase Whatever This Is
Galadriel's Dismissal is another spin on Teferi's Protection, that can be used aggressively. Probably not worth it, though.
If you watn to go down the combo road, Legolas's Quick Reflexes is a great option to get additional value out of Selvala. Mana, life, card draw AND removal?! Sounds nice. But it's not for this deck.
Wilds of Eldraine
Stroke of Midnight is anotherBeast Within, that leaves a smaller token but can't hit lands. The token isn't relevant in most cases, so this feels just worse. More options are always welcome, though.
End-Raze Forerunners got another cousin in Moonshaker Cavalry! Unfortunately they lack haste, so you're missing out on 6+ damage. I'll stick to my beloved boars for now.

Some smaller changes:
Dawn of Hope returns, while The Gaffer needs to go. I don't hit 3 life as reliable as I hoped. So for the moment Dawn is back. I think I want to play The Great Henge on this slot, but yeah. 40 € is way too much. Maybe I manage to sell some other cards.
I want to reasses, how good Mana Reflection is. Mirari's Wake has been great, but doesn't send Selvala into space like Reflection. We'll see, how much my friends like this addition^^
