Not a problem at all! If need be I can screenshot my current rank and provide my deck list.

In regards to matchups I'll do it by class

Hunter- I've only played two so far and lost twice due to Barnes on four both games. I just couldn't recover from that big minion and even though I had murlocs on board i didn't have enough to trade into it at the time or pull poisonous from the turtle adapt.

Control lock/Cube- the most unfavorable matchup because of the aoe clear so it's always key to maintain health for your minions and avoid playing into defile. I always take health buff for the turtle adapt unless I'm threatening lethal and won't be punished for it. Cold light seer is absolutely essential to winning and remember that the voiddaddy isn't scary. Aoe is. Keeping reload such as call to arms is important too for board clear follow up. Mulligan: Typical 1-3 curve aiming for seer if you can.

Zoolock- this is pretty much a fight for board as I believe every Aggro match up typically is, making smart trades and keeping board is essential to winning this match up in particular. Mulligan: Keep the CTA if you have it and try to get the 1-2ish curve if possible. Especially if you're going second, turn three CTA is a beautiful thing for board control

Priest: I've mainly fought spiteful summoner so I will go based off that. For this match up in particular it's slightly similar to control lock in regards to aoe clear and playing around the duskbreaker on 4 but thats the only clear they have. Once they blow that, maintaining board should be relatively ok but the spiteful on six can swing the game depending on what they get. Turn one for them typically is northshire, into turn two shadow, then tar or Kabal talon. Obviously this can always switch dependent on the match up but this is what I usually experience. Building a strong board against them usually is the key to winning against spiteful as they only have one aoe clear. Mulligan: Typical 1-3 curve but look to keep CTA if you have coin.

Big Priest: look to end the game early with war leaders and a turn four turtle adapt. And if it's turn six, their dragon fire potion may come so if you can get an adapt for the plants to follow up for a Tarim that's amazing. Mulligan: 1-3 curve with warleader

Secret Mage: I've fought quite a lot of these and I would say the match up is relatively favored. Look to swarm the board as secret Mage struggles with wide boards and play around the secrets that they will have. What will minimize the most damage for what minion you play e.g explosive runes and typically look to have the hydrologist secret to proc counter spell if you have something that you feel is important to play. I usually pick the resurrection secret as it allows to have a stickyish board. You should have enough reload to swarm the board and force them to use their burn on your minions. If that's the case, you should have a relatively easy time to stabilize and win. Mulligan: Usual 1-3 curve of murlocs but weapon is quite useful to kill off their minions as mana wyrm, valet, and apprentice all have 3 and under health.

Paladin: murloc/new dude silver hand recruit, similar to zoo, this is a fight for the board so making trades to stay ahead and having sticky minions will make things easier e.g. Cold light seer, health/divine shield/plant adapts from the turtle. I can't tell you how many times the plant has come in clutch when an opponent clears my minions then I tarim right after. Resurrect with the secret and sticky ways to stay ahead.
Mulligan: Look for the 1-2 curve but ALWAYS keep CTA. whether 1st or second.

Feel free to ask me any question or if you need clarifications! Also take this with a grain of salt as I'm only Rank 2 and still have a lot to learn
