I personally run fabricate, to get thousand-year elixir faster

I included days undoing to reuse the stuff in my deck, kind of like a Timetwister but there is no way in hell I'll ever get one, so I chose Day's Undoing . I think Fabricate is a decent idea, however you just grab Trophy Mage anyways, so it doesn't really matter. She is also tutorable so I feel a 3 mana tutor at sorcery speed isn't the greatest. Plus, the deck is really tight as-is.

Day's Undoing isn't a reasonable replacement for Timetwister. Honestly, there is no Twister replacement. If you can't afford it just run a different effect, not a worse Twister.

I understand, sometimes it is really hard to find a replacement for cards like that. So kudos for actually finding a decent replacement

I actually think the best replacement for it is Thrasios, Triton Hero . That way, when you have infinite mana you can draw your deck out and Laboratory Maniac for the win.

is there an other wincon once you have infinet turns ? because beating your group to death is well not done in my playgroup because of the aggro heavy meta.

if you are deadest on not beating everyone to death, then throw in Beast Within and Reality Shift and loop them with Eternal Witness to mill everyone out. also gives more removal, at the cost of a little more synergy and consistency.

Could you explain the new tribute mage combo to me?

Corridor Monitor is a good 2 drop addition to substitute, since it removes the requirement to return a forest to hand!
