What do you think of Blue Sun's Zenith as another win condition for your deck?

kilgore: Blue Sun's Zenith just isn't good enough on its own. If I have infinite mana, I just use Tasigur and win. He's in the command zone and easily accessible, BSZ requires it being in hand to take advantage of the infinite mana.

If I do have infinite mana and have Tasigur then I have all non-land cards from my deck and I can cast them an infinite number of times by casting, then activating Tasigur again to get it back. From there I can either repeated Beast Within everything of my opponents, then Reality Shift all of my opponent's libraries away and Timetwister to instantly win. Or can Palinchron infinitely for Aetherflux Reservoir triggers to get enough life to kill all my opponents with the Reservoir.

Make sense?

Thanks man. Are you discussing this list on r/cEDH anywhere?

At current outside of Tapped out, no. I am working on a primer for it and the play style behind it. I was planning on MTGS and Reddit when that gets done though.

If I'm trying to build this deck on a budget, is Day's Undoing a reasonable replacement for Timetwister, or should I simply neglect that effect and play something else?

Also, I really appreciate the content you guys produce on your youtube channel. :)

buildingadeck: Day's Undoing can work. Having Twister in the yard is a really big plus side to it. Also Day's Undoing ending your turn does hurt a bit. However, from a budget perspective it does work, it ticks the big boxes that Twister does for you, it draws 7, restocks your library and messes with your opponent's hands. If I had it in the deck I'd do my best to use Alchemist's Refuge to cast it at the end of someone else's turn though.

That is a smart play. If you have a moment, I'd love if you could check out my budget list: Yay!

I'm tinkering with Getrekt Leviathan as a budget monster, and it's so good with Aetherflux Reservoir and a couple Artifact ramp sources. I realize you cut it, but I am still curious if it might have a slot.

Also, Mystical Tutor over Vampiric Tutor seems strange unless you're worried about the lifeloss.

buildingadeck: Good spot on the tutors. You are correct, Vamp is just better than mystical. It is getting the swap out now. It got cut a long time ago when I took Imperial Seal out as well. Tutors to the top of the library aren't as good as to hand as they do not work with Seasons Past + Omni.

I'm looking over your list now and will comment.

In my Atraxa list, which wins similarly, using an infinite mana combo or omniscience to cycle seasons past and a to-hand-tutor, I run Think Twice, as it enables the combo to work with to-top-tutors, and on it's own is an instant speed cantrip with potential late game upside. Have you at all considered Think Twice for this reason?
