I am working on a standard 'tempo' esque deck that i think will be my pride and joy. What should i be wary of in current standard that may cause tempo a major issue? Ive never exactly made such a deck before but i understand its basically aimingto get the most value of every card, and outvaluing my opponent each play. Standard isnt horribly geared for that at the moment, especially not the colors im using, but i think im onto something. I just need to know what the issues and weaknesses might be of this type of deck, as related to standard.
Tempo involves not letting your opponents get past the first stage of the game, while you outpace them by always being one step ahead. To do this you need cheap resource denial. Unfortunately standard right now is rather short on that. You don't have good early mana denial. You don't have any good cheap counterspells. You don't have evasive/hard to kill threats that cost less than 3 mana. It will be hard to build a good tempo deck in a format centered around "Devotion", which entails a format centered around late-game spells. However, it won't be impossible. I think an esper tempo deck might work.
Use {Llev Skyknight} as one of your best threats. {Pain Seer} is a must-answer early drop. Untap it and you just 2-for 1ed your opponent. {Deathrite Shaman} should be tested. Ignore the green. You wouldn't use that ability anyways. {Springleaf Drum} is a good tempo card and needs to be tested. {Thoughtseize} in the mainboard might be good. {Syncopate} is your best bet in the counter department.
Good luck and remember that tempo isn't control. Don't think late game. Think about killing your opponent and being 1 step ahead. Don't overextend into {Supreme Verdict}, but don't be too careful. Take advantage of power plays. Make the most of your opponents' mistakes and make sure you don't make any of your own. Mistakes cost you if you are piloting tempo.
Im thinking of trying to make a golgari tempo deck, dont judge me!
Well, I mean you have {Abrupt Decay} which is a good tempo card. Cheap. Flexible. Everything you want. But other than that I don't see black/green as the best tempo build. Green has so little to offer when it comes to tempo. But not saying it can't work. Just don't be surprised if you come to a dead end with those colors.
I will not fail, i MUST NOT FAIL
That's the spirit!
