Renolock deck plays incredibly funny as you climb in ladder. The only real downside is long long *fatigue* long battles with other control decks. One can play 6-7 with agro deck while you in some match-ups draw up all 30 cards and the game still goes on.

This deck uses Lord Jaraxxus and Ragnaros as a win condition against control deck, putting strong presure on the table. And has a lot of board removals and taunts against aggro match-ups.

While internet swamped with different variations of renolock decks, below i would like to share my experience in playing this deck in different match-ups and explain why i think some cards fit better then others in current meta.

Some cards which are often playable in Reno decks i dont play now:

1. Soulfire - some players consider this card very good for agro decks match-ups, especially shaman, when you have to remove early healthy overload minions. However i don't like it's downside effect which might result in loosing Kazakus or Reno Jackson , let alone other useful cards which you might need 2 turns ahead. 

2. Shadowflame i think it mostly benefits from Power Overwhelming , Leeroy Jenkins , Alexstraza reno deck. And for this deck there are some better options.

3. Alexstraza card seems to not work for me in this deck, because we don't have any strong finishers to fully utilize it. 

4. Blastcrystal Potion - this card if played until turn 9 puts you in so huge disadvantage, especially if start with coin, that literally you can't deal with opponents treat and keep up with tempo. Remembering a lot of agro decks in the meta, does not work at all.

Cards i think "must have" in the current meta:

1. Kabal Courier - this card is one of my favorites, it's very versatile with always good options available, which will fit your current board position.

2 Dirty Rat - card is very strong in current meta, as we are facing a lot of agro decks, it also works exellent against control decks, if you feel moment is right you can mannage to snatch opponents Kazzakus, Reno or ruin some combo. It can contribute a lot towards wining the game. The only matchup i try to avoid drawing it in starting hand is  with shamans, usually you end  up puting 7/7 of 3/4 on the table.

3. Felfire Potion - VERY strong AoE, clears literally everything if played at turn 6.

Match-ups.

Easy match-up for this deck, unless you are unlucky with your starting hand. At mulligan you should aim at cheap cards asVoid walker, Doomsayer, Mortal Coil and Acidic Swamp Ooze
