This is my "Budget" Ramp Druid deck. I was also able to beat Anub'Rekhan & Grand Widow Faerlina in Normal/Heroic Versions with this deck.

Mulligans

You will always want to Mulligan for Innervates and Wild Growths. This is even more important if you go second as you can use The Coin + Innervate for a first turn Chillwind Yeti, or if against aggro Keeper of the Grove.

Strategy

1. You want to be as mana efficient as possible. This means don't use Wild Growth on a turn you have nothing to Ramp up to on your following turn.
2. Use your Keeper of the Groves for instant value, if going against aggro to take down board threats like Flame Imp for instance, of if going against control using it on a minion to silence such as Cairne Bloodhoof to get a big tempo swing back in your favor.
3. Use your Ancient of Lores as a Card Draw Engine to gain card advantage over your opponent, or if in a pinch as a +5 Health heal while simultaneously putting a 5/5 on the board for more board control or presence.
4.  Don't use your Swipes & Wraths too hastily, while getting through 1 big threat is nice in itself, not having the potential AoE or Card Draw later on can hurt you. (Remember the key is Maximum Value)
5. The general idea is to be as mana efficient as possible while constantly getting value from your minions & spells and setting up taunts, thus stone blocking your opponent into submission.

Replacements

Most of the deck is solid and works well even with the threat of The Black Knight & Big Game Hunter. That being said both Ironbark Protectors &  1 Mark of the Wild can be swapped out if you happen to craft or get any of following cards.

1. Ragnaros the Firelord - With so many taunts and the sheer value you can get adding him to the roster is a no brainer. Not only have you baited most if not all removal by your opponent by then, but an 8/8 with RNG 8 Damage is very strong, and compliments your control style well.
2. Ysera - Just like before she's a no brainer as well. The biggest weakness in this deck is that you must try and maximize the value of your cards as much as possible. Ysera brings extra potential by giving you a random card; 2 of which are great minions for their mana cost, 3 of which are situational and very powerful spell cards. Increasing the strength of your deck even further.
3. The Black Knight - Including him in your roster allows you be more lenient when it comes to getting max value out of your deck. This deck doesn't have any direct removal, and sometimes getting through a Taunt, specially a big one is almost invaluable.
4. Cairne Bloodhoof - Adding him to the roster further emphasises your deck towards getting the maximum value possible, not only is it a strong minion but with the deathrattle in addition to [cardMark of the Wild[/card]s theres a potential for 2 extra 6/7 taunts to be added to your deck. More taunts equals better chance of winning in this deck.
5. Sylvanas Windrunner - Adding her to this list makes this deck extremely lethal. Not only do you control very hard, but with her on your roster you have the ability to choose which and when to steal a minion from your opponent.(Very Scary Stuff)
6. Maexxna is another possible replacement for the roster, as a Ramp Druid she can be very useful if you can take her out rather quick with Wild Growth & Innervate, and has the potential to trade very well with her ability and with Earthen Ring Farseer & Ancient of Lore you can keep her healthy for even more potential. Coupled with Mark of the Wild & Defender of Argus, plus the insane amount of taunts it can stay relatively safe or be used to force your opponent to either make trades they don't want or force heavy removal which is always a plus.
7. Blood Knight - Since you have 2 Sunwalkers on the roster, adding him to it is not so farfetched. Sure you remove the strenght of the Sunwalker by taking away his Divine Shield, but this adds yet another big threat to the board for your opponent to deal with.
8. Big Game Hunter - Adding one of these for your roster to deal with the big threats that you can't deal with when facing such decks like "Handlock" is another distinct possibility.
9. Violet Teacher - With the influx of low cost spells adding her to the roster is not a bad idea. She has great flexibility and can create minions for you for extra value with Mark of the Wild.
10. Power of the Wild - adding these to the roster can help balance the curve with so many high end, by giving you the ability to either buff current minions or make a 3/2 so you can have early board presence while you set up your ramping to your bigger and strong threats.
