That a tough question as I like the playstyle that every color brings.
Golgari utilize the graveyard so well that, at times, watching them play feels like they are cheating. bringing things back from the graveyard and making them more powerful as well. it like watching a
dredge deck go off, all you can think of is "is he killing himself? What is he doing?" and then all these creatures start hitting the board followed my a flamed zealot.....
Orzhov is a guild that i haven't seen very often but i can never
forget recurring
angel of despair, that definetly won't fade.
Selesnya, the token makers! At least that is what i thrived with.
glare of subdual and
vitu-ghazi, the city-tree was awesome back in the day! one of the first instances that i came across of tapping a creature that just came into play, that turned into a rules
nightmare LOL!
Boros was, is and will always be fast! hasty drops with double strike just scream Boros! Plus
lightning helix is the bomb in my eyes ( tip of the hat to Warleader's Helix ).
Azorius had some good moments but what never run alone, at least from what i remember.
Lightning angel decks would used to rule the skies! even now
supreme verdict and sphinx's
revelation makes everyone cry...
Gruul will forever be the base for great zoo decks. just spew out creatures that get in there!
Dimir has dropped in power from the old milling days when
Glimpse the unthinkable was around. Follow that up with a
guiltfeeder and GG.
Rakdos I also don't have much experience with but i remember hating when
Bladewing the Risen hit the field, of course that was pre
dragonstorm...
Simic has some of the most interesting counters i can think of. Mystic snakes was such a badass and lets not
forget my favorite simic card:
voidslime !
Manaplasm has to be my standard favorite.....if i can ever get it off!!
Izzet....I think its a bit obvious that i have left my favorite guild for last. Izzet has been my favorite color combination since before there was an Izzet guild. Blue and Red has my all time favorite cards in it! Timestop,
temporal manipulation,
theft of dreams,
propaganda,
arcane laboratory,
bribery,
Teferi, Mage of Zhalfir ,
venser, shaper savant, War's Toll,
mana geyser,
demonfire,
molten disaster,
manabarbs,
sneak attack,
warp world,
Pandemonium.......i can continue this forver! Big effects in single spells is so attractive to me as is the opposing forces that run an Izzet deck make me an Izzet Fan for Life!!!
