Nightange1 - I'm running Crucible of Worlds because there is a fair amount of land destruction in my meta and this will get me around that.

Emory - Looking at your tutor suggestions I don't really feel the need to run Mystical Tutor or Personal Tutor , but I would definitely consider Vampiric Tutor . And could you be more specific on which redundancies are inefficient?

I guess by redundancies I'm trying to figure out why there are so many creatures in the deck. Do you want it to be competitive or damn near unbeatable? My sydri deck runs 18 creatures and I'm trying to cut it down to like 11 and even that seems too much. To be competitive with sydri is basically the same with all esper generals. Less creatures more control and tutors so you can get into combos faster.

I don't see anything in the description about the infinite combo between Power Artifact and Basalt Monolith . Its pretty dope. Grim Monolith is along the same lines, if you can afford it.

Unforgivn_II - I guess I should mention that, huh? Power Artifact + Basalt Monolith + Staff of Domination is one of my win conditions. I'm considering adding Sharuum the Hegemon + Clone effect + Disciple of the Vault as another win-con, along with more counterspells (Assert Authority , Stoic Rebuttal , Spell Crumple , Hinder , etc.). Otherwise the deck has performed well for me. Any other advice?

Um, Voltaic Construct + sydri + a mana rock that taps for three?

hey, check this out.. you could fin interesting ideas in there:

Ensoul Artifact ?

Chargingbadgerrrrrrrr - Ensoul Artifact exposes an artifact to sorcery speed creature removal, which is something I really don't want to do in this deck. Also there really isn't anything I would cut for it.

Something I've been noting on a few other Sydri decks is the inclusion of Akroma's Memorial. This gives all your creatures pro-black and makes them untargetable by Sydri. May or may not want that, Memorial is still nice, but locking out your general from doing anything but animating non-creature artifacts is not so fun.

That's a valid point Necrotize, but you hardly ever use Sydri, Galvanic Genius's second ability. I'd much rather have a 9/9 Darksteel Forge than one with lifelink and deathtouch too. The only time that hurts me is when I'm trying to use the Caltrops + Sydri, Galvanic Genius combo. In this case the pros outweigh the cons, but the Memorial could be on the chopping block should something better come up.

Sword of the Meek Thopter Foundry

Selcath - Would you care to elaborate why I need those two cards in my deck?

Because it those two cards are a fantastic combo in a Esper artifact deck. I ran them in conjunction with Ashnod's Altar in my Sydri deck, and it was a very nice infinite mana, and creature combo.

Dross Scorpion would allow you to untap mana rocks or Myr Landshaper when you destroy lands with Sydri, and let's you infinitely destroy lands if you use it to untap a land of your own while Mycosynth Lattice is on the board.

Rogue_Toaster - I talked previously about why I'm not including Myr Landshaper, as Mycosynth Lattice just does the job better.

I'm not sold on Dross Scorpion yet, but I'll see if I warm up to it.

I feel like Sydri, Galvanic Genius doesn't get enough attention compared to someone as boring as Sharuum the Hegemon.

Yeah, Sidri suffers from the fact she isn't a part of a ridiculous infinite combo that kills the table. But I do enjoy having Sidri over Sharuum for shenanigans like Caltrops

Yesterday I dropped the Thopter Foundry, Sword of the Meek, Time Sieve and Ashnod's Altar combo. It was fun. I won immediately. I thought someone would stop me but I guess they didn't have any responses to all of that.

I didn't see if anyone suggested it, but sydri plus aetherflux resivoir is a great combo, and can take everyone out at once and (theoretically) if it's a multiplayer game

Don’t forget the combo with sydri and staff of nin it’s basically destroy target creature

So I have just 3 cards that I feel should be and auto include [Ursa, lord high artificer] your mana will be silly. [walking balista] with sydri is amazing and the most important is [aetherflux reservoir] giving this lifelink and deathtouch allows you to machine gun down your opponents
