I can't get past Rank 15 (and currently am struggling at Rank 18).
Now that there's more incentive to have a higher rank at the end of the season (rank chest) can anyone tell me how I can improve on this deck? I don't have Sylvanas or Antonidas.
While there are ways to improve this deck, you shouldn't have a problem climbing rank 15-18 with that. 3 star ranks are just too easy to climb up with win streak. To what kind of decks you mostly lose?
Cut a secret, one mirror entity is enough. Tempo mage style of decks are very draw dependent, you don't want more possible anti tempo cards in your hands. The secret is only good tempo when mad scientist plays it. ME doesn't bring much value these days as it's a first thing any one expects. You need to make room for arcane missiles instead. I personally prefer water elemental to shredders these days, it's hard to kill and destroys weapon classes. You need arcane intellect, dragons are not enough.
I suspect in a lot of games you bring the opponent to like 10 or so life but lose the game cause you can't finish. Well you don't have a finisher. Since legendary cards are out here, maybe you can add a pyro?
Overall if you ask me, any mage deck is garbage for laddering right now. You need a consistent deck, with great drawing engine or curve that no matter what you get things you can play for significant board impact. I climbed with tempo mage to 5 on EU and it was all luck in those last games, winning by one health, stupidly good top decks and things like that and I even had iceblock to last one more turn.
Mech Mage I feel is better right now, tempo mage is way too inconsistent and wastes your time by ruining winstreaks.
For laddering in general, you must have some card knowledge too, like what every class can kill you with, what is their possible next move, what exactly they are setting up here, or guessing what is in their hand, what they are keeping, what they are top decking. I feel if you want to be more successful in ladder you must try all the other classes too. I noticed you just play mage? that's quite limiting.
If you can't do that, watching streams really helps improving your game knowledge and your plays. Watch StrifeCro or Kibler, these two explain their moves and thought process really clearly and both are really fun to watch, K. See what they do and what you would have done instead, doesn't matter if their decks are different, the rules of trading, tempo and game knowledge applies to any deck and they face deck similar to yours and you see other players of high skill playing against them, see how they open, how they trade, when they hero power. all of that.
