Can be competitive or casual. Can be any format you want. No need for a list, but a little explanation of why you liked it should be provided.

For me its Onslaught-Mirodin standard era Astral Slide. I started getting interested in competitive constructed during the Onslaught/Odyssey standard era, but it was towards the end of that format so I didn't get to know it that well. I was mostly playing terrible brews (mostly WW) and getting destroyed by anything and everything. I kept forcing WW in early Mirodin and it kind of worked. Of course, everything kind of worked when you threw 4 skullclamps in it! Eventually clamp got banned and my WW deck started sucking. Then darksteel got released and I finally gave up. Played ravager affinity for a while and once I got a taste of netdecks, I couldn't go back to the **** I played before. Everyone else was playing ravager and that got boring. That's when I discovered eternal slide. That thing was just pure beauty. Playing against aggro? Wrath every turn. Playing against control? Plow under every turn. It even had a built-in tech against ravager, because if they dump every counter on one creature, you can just slide the creature and get rid of them all. That wasn't enough to beat ravager on its own, but when viridian shaman was added to the mix, I felt slide had a pretty good matchup against affinity. The beauty though was that it was super consistent because more than half the deck could be cycled. Add to that a bunch of other small synergies (slide + duplicant, slide + solemn, slide + exalted angel, etc.) and I was in love. I don't think I ever had as much success in constructed as I had with that deck. I loved playing it, I played it perfectly, I was winning, it was a dream.

Runner ups:

- Pirates, for two reasons. First, because you get to play pirates, second because when will you ever play a mono blue LD deck?

- WW: It was the first deck I ever built that made sense (i.e., not a 5 colored pile with no strategy). I've evolved this deck in casual since 1995, although not much is left from the original deck other than my stp's and a few pump knights.

-Enchantress Combo
-Dyrad Sligh
-Kobold Combo
-Sunrise Eggs
-Manaless Ich

EDIT:
Years ago the casual forum had a guild wars competition back when Ravnica came out. Had an awesome u/w Dovescape combo deck.

I played Enchanted Evening +Patrician's Scorn/Spring Cleaning in standard for a while. I don't think I've ever had as much fun playing magic

Dragonauts/Kiln Fiend has got to be the most satisfying deck I've ever played. Assault Strobe and Distortion Strike are plain evil, and will usually be the key factor in getting you to deal 20+ damage in a single turn. The variant I built also included a few flashback spells like Artful Dodge, Deep Analysis and Reckless Charge, which synergize quite nicely with the concept of the deck.

That sounds super budget friendly too which is nice. Hmmmm

Stax.

It's extremely budget friendly, I think there are more commons than uncommons and rares combined. In fact, I believe the only rares I actually put in it were dual lands. I'd check, but I lost my deck list a little while ago

So arguably the most soul sucking deck of all time.

(1) Any MUD variant.
(2) Any Eggs variant.
(3) Any Elf Tribal.

~SE++

You know me.

Haha, I didn't see your quote at first, and I thought you were talking to me.

Anything's budget friendly when you've got cash swag B^)

Not 60 card, mind you, but I've got a soft spot in my heart for my Niv-Mizzet EDH deck. It's the most consistent combo deck I've ever built (at least as consistent as 100-card singleton can be ), and it gives me a chance to just combo kill my friends if they've been annoying me enough.

Skyshroud Cutter
False Cure
Grove of the Burnwillows
Kavu Predator

+ the many cards that finish it up. I'm always looking for new cards to make it even better.

Oh, I've always liked False Cure decks like that. For a while, I had the Intuition/Life Burst combo running with it. What really got saucy was using cards that were already good with the combination. Nothing is quite as fun as casting Swords to Plowshares on a creature you just Invigorated. Very inconsistent deck, but tons of fun. I even had a version trying to abuse Roar of Jukai.

My favorite decks are always the Johnny decks that end up actually working. My top five:

5. 5-Color Oath

Mirage/Tempest standard deck that used Oath of Druids with creatures that die like Spike Feeder and Ball Lightning. Oathed every turn, had ways to lock down the opponent, had the most painful mana-base ever, but brought me by first bought of success in Standard.

4. Necrotic Ooze combo

Similar to the deck Conley played. raz and I figured it out together. Made it the day Ooze was spoiled. Here's what it looked like.

3. Mesmeric Orb/Aphetto Alchemist

This deck was the Nomads en-Kor/Cephalid Illusionist deck before that deck was a deck. I worked very hard to make that thing work and it was beautiful. One of those moment where your playgroup stops looking at you weird and starts thinking "This guy's on to something." Played it at PTQ Kobe, but I didn't spend enough time playing the deck to navigate it well enough. Still, fun times.

2. Gnawed Thoughts

Only actually played with this one a few times. The only reason it makes this list is because it one the deckbuilding competition Adrian Sullivan issued. This article explains it. I'm idiotic_puppy, the deck at the very end. (That was one of my early email accounts. I still use the name for my photobucket.)

1. Anything from Innistrad limited. Seriously, I must have made 30 different archetypes in that one environment. So much fun.

Actually, while I'm making cash money now, I've traded for most of my stuff. I bought one workshop and my jet outright, but all of the other expensive stuff I own was traded up to. Most of my magic expenses over the years have been boxes.

who exactly trades power for anything else?


i have a bazaar, some fow's, duals and other stuff in storage somewhere, but never got around to bother selling them.


when i was 15, i had the opportunity to buy a full set of (real) power from this kid i knew (he had no clue) for ~20 dollars. i didn't have cash on me at the time and by the next time i saw him again (a year later) he had lost most of his cards.

karma i guess.

My smartass response would be the m14 sealed deck I played to my PTQ Top 8 last month.

I had a lot of success with Ravager Affinity because the deck was so easy to play. I actually found it fun too though.

My favorite decks were the stupid samurai garbage that I used to play. I haven't really had a deck since coming back that I found insanely fun. Maybe this Mono Brown Tron deck I made in modern or this UR Tron deck that was built around Panoptic Mirror.

I know one of my favorite Magic moments in constructed recently was playing mono-white belcher in modern and my only out to win was hitting 10 cards with Belcher naturally (the deck gets rid of all the lands with Endless Horizons) and hitting 11. That was some of the craziest stuff I've done.

My Un-deck that somehow scores t-2/3 kills on a regular basis with Blacker Lotus and Garfield, not to mention ______ and Now I Know My ABCs.

Nightmare Survival
a.k.a.
Recurring Survival
RecSur
Cali Nightmare

For those that don't know it was a combo deck that came about with the release of Exodus, that used the amazing synergy of Survival of the Fittest and Recurring Nightmare.
You basically ran some BoP, Wall of Blossoms and a bunch of silver-bullets usually winning the game with Spirit of the Night. The deck has only gotten stronger thanks to some of the current creatures in MTG;
Some examples;
Vengevine - Gives the deck a semi-aggro option similar to the lists that got Survival banned, that also lessons it's dependence on RN.
Kokusho, the Evening Star - Self explanitory; especially effective when combined with Great Whale/Palinchron
Ashen Rider - Angel of Despair 2.0 has amazing synergy with RN.
Iona, Shield of Emeria - Again, no explanation needed.
The Praetors; namely Elesh Norn and Sheoldred - just adds another level of control.
I could go on, but the point is clear; the deck has a lot of options and is quite strong.
