Question

what is the best strategy for each of the following decks

black/white

red/black

red/green

blue/black

white/green

black/green

white/blue/black/red/green

Answer 1

Black/White – Gain a ton of life, stall the game, then bleed your opponent bit by bit to death.

Red/Black – control the board, burn out anything that looks threatening, stall, then pain your opponent to death with more burn spells or black life-loss spells.

Red/Green – Rush out with fast, cheap creatures and finish up with some burn for the crucial last few points of damage. I currently play this deck, and it is very fast and very furious. Get your opponent from 20 life to 0 life as soon as possible.

Blue/Black – control the board through counterspells, occasional mass removal (Damnation) and play out a huge threat that can’t be dealt with by your opponent for the win. (Faeries: Counterspell + Bitterblossom + Cryptic Command + Mistbind Clique = Win a lot of the time.)

White/Green – Ramp up mana, play big threat (Garruk Wildspeaker, Oversoul of Dusk) and beat the h**l out of your opponent.

Black/Green – Control the board with discard spells and removal. Terror removes any threats, and when your opponent is out of options, play a big creature (Doran, the Siege Tower or Chameleon Colossus) for the win.

All five colors – a bit of everything, counterspells (Cryptic Command) Card advantage (Careful Considerations) Board sweepers (Cloudthresher, Firespout) and reanimation (Makeshift Manniquin) VERY GOOD DECK by Mr. Wafo-Tapa, the renowned constructed master of France.

Hope that helped!
