Stardragon on All the combos

I'm making a 5 color combo deck stuffed with ad many infinite or instant win combos as possible. I already have Grindstone/Painter's Servant and Acererak the Archlich/Omniscience. Any fun, salty or wacky combos are welcome

Yeah, it's a lot of the same ol shit, defending against Ragavan, Nimble Pilferer, Dragon's Rage Channeler, Orcish Bowmasters, Deathrite Shaman, The One Ring, Necropotence, Omniscience, ya know. When I go up against something else, I'm usually pleasantly surprised. I mostly play aggro builds and BO1 matches, I like the games to be quick and fun as I don't have a whole lot of free time, and def not enuf for a BO3 control match. I could get into some Brawl again tho. I do have a bunch of EDH decks built on paper, and a couple brawl decks on Arena that I haven't touched in quite a while, but I do enjoy the format. I sent you a friend request on Arena, Same username as on here.

The story behind this deck is so cute, I love it. Let's get to it.

The first thing I noticed when evaluating the potential consistency of this list is that you need to trim some fat from your gameplan. Personally, I'd cut down to 30 lands, include a list of mana rocks & mana rituals, dial into the key pieces that are actually going to win you the game like Windfall & Ojer Axonil, Deepest Might  Flip by cutting stuff like Omniscience & Price of Knowledge for tutors like Mystical Tutor & Vampiric Tutor.

If you'd like, we can strip the list down and rebuild it from scratch together, I love Nekusar lol.

Thanks Imaginary_Friend777!

You make a good point with Clear the Mind, it’s not really vital to the game plan. I just had it there for the sake of having an infinite loop but it’s kind of a waste of main board slots, especially since I have two in the sideboard that I could grab with Mastermind's Acquisition if I really need the loop.

I like your suggestion of Aetherflux Reservoir over Grapeshot and I think you’re also right about needing more counter spells to protect my Omniscience once I cast it.

I think I’ll try taking out both main board copies of Clear the Mind, but I’ll leave the sideboard copies in because I’ll still need them since I’m probably gonna need the option of an infinite combo if I go with Aetherflux. Then I’ll take Grapeshot out completely and just replace the sideboard copy with Aetherflux, and then I’ll add one more copy of Mastermind’s Acquisition and two more copies of Test of Talents to the main board.

Thanks for the suggestions!!

Creative Technique, perhaps? Omniscience, maybe also? Funny list :)

NV_1980 I have been back and forth on things to cut and add in this deck including mana dorks. I would like to add one, if not both of them. Any suggestions on swaps? Currently the deck works on an Omniscience + Conflux line for an instant basically un-interactable win. I find value in almost every card at the moment so outside insight would be appreciated.

Caerwyn on is Omniscience a triggered ability …

First off, please link your cards using double brackets, like so:

[[Omniscience]]

Omniscience

To answer your question, it is neither--it is a static ability that is always applicable. Here is the rule:

604.1. Static abilities do something all the time rather than being activated or triggered. They are written as statements, and they’re simply true.

Activated abilities will always have a cost, followed by a : followed by an effect. Triggered abilities will always use words "when", "whenever", or "at", followed by specifying a condition for the trigger, followed by the effect.

A controversial substitution perhaps, but deserved

Replacing Omniscience with Moonsilver Key.

Why not Omniscence?

  • Omniscence is too mana intensive in this deck. In your opening hand it is completely a dead card 90% of the time. In the 10% you have a line to play it in your opening hand, you are putting all your eggs into 1 basket. Omniscence is too high risk for the reward. If this spell doesn't resolve (and it likely won't at a cEDH table) you lose the game.
  • Even the times it does resolve in the early game, your hand doesn't always have enough steam to win outright.
  • It is important for all cEDH decks to consider how a card will function in your opening hand as well as later in the game. I'll write more about this topic in the current theory module of the guide. This inconsistency in the opening hand is what makes it bad. It is true that other cards in the deck are similar, but they aren't as mana intensive as omniscience. Omniscence in my opening hand has lost too many games.
  • Omniscence is essentially a combo by itself while Unesh is on the field. It is clunky at best because it doesn't always guarantee you get to the bottom of your deck unlike Rite of Replication. Recent powerful revisions of the deck have led to anti-synergy with this card. Example 1, removal of Long-Term Plans. Example 2, the addition of Palinchron makes infinite mana and storm more attainable than with Omniscence due to the reduced mana cost.

Why Moonsilver Key?

  • I think this card might be as much of a blindside to you as it was to me. I knew Omniscence had to go, so I started researching what I would replace it with. And I found this card. This card is the most opposite of a clunky opening hand card I could find. Rather than having a dead Omniscence in your hand, you can spend your early turns playing this card and getting an important mana rock like Jeweled Lotus & Mana Crypt or an Island.
  • The deck has been short on mana rocks. With a mana rock tutor in this slot combined with Virtue of Knowledge and fetch lands I have noticed a significant uptick in ramp reliability in my opening hands. I have been throwing around ideas like Mox Diamond, Mox Opal, and Mox Amber but none of these cards reliably solve Unesh's problems in the opening hand. I also considered Lion's Eye Diamond which seems a little too high risk IMO, because then your fate relies on the subsequent BFOF from casting Unesh. The runner-up contender was Fellwar Stone, essentially a worse Arcane Signet wouldn't be bad. It is important for Unesh to ramp out ASAP, and having a mana artifact tutor in the early game seems to help with that plan, and it thins the deck.
  • Minor point, it enjoys synergy with the adventure mode of Virtue of Knowledge.

What are your thoughts on this sub? Could I be doing better here?
