I want to talk about the way I view Scholar for a little bit. He is by far one of my favorite decks to play. This guy weilds serious power, and finding the best ways to unleash it are not always easy. The core of the deck surrounds his three forms so utilizing them effectivly is the key. The question we have to ask is "How can I sustain a lot of those?". Lets talk about the Liquid Energy Engine (LEE for short).
Starting the Engine:
Let me preface this all by saying that it is always best to play to the situation you are in. However, we are looking for a few specific things in the begining of the game. Lets talk opening hand. If there is one totally and absolutly nessesary component to the Engine, it is Bring What You Need(BWYN). Not only is it essential to keeping your hand size large, but it lets you cycle the elemental form cards back into the deck (more on that later). If you do not see it in the first 4 cards (and chances are you wont most likely), then we need to start thinking about how to get it. Truth Seeker is a high priority card to start netting cards (hand size is obviously important. The more the better). If you are able and have the choice, hold on to your Transmutive Recovery's as you will want as many as possible later (but dont be afraid to use them if you need to dig through your deck faster). Stay clear of Don't Dismiss Anything. Yes it can be useful sometimes, but not every hero is going to like playing random cards and the Engine hates a surprise Know When To Turn Losse. That needs to be avoided if at all possible. Flesh to Iron is an option to help stall while you look for BWYN, but you have breathing room with your HP and Iron will slow your hand growth.
Getting up to Speed:
Once you find BWYN, use it often and always. No more need for TSeeker, we will be doing enough damage soon. BWYN helps keep his energy forms in his deck so that Keep Movings can play them for free and will net you 3 cards a turn considering your draw phase. Your play phases now must focus on getting your forms out. The target goal is to get two Energy Forms and one Liquid Form to start. That ratio gives you the most bang for your buck, although starting double liquid and one energy is usefull for passing DR. You should now have a decent hand size if you wernt feeding rouge forms early, and BWYN will sustain these 3...if you don't play cards. So what now?
Feeding the Engine
Trans. Recov is the main fuel and it works well. With the base engine going, you will gain 3 health and belt out 3 damage twice and draw 2 cards. This also allow you to support a 4 form Engine compfortably (3:1 energy to liquid is your best damage output but 2:2 provides punch against DR). Proverbs and Axioms is also prime fuel. Although it does not give as many cards, you can either heal/damage for the same amount. Scholar might regain too much HP at times, and if he cant heal, he cant damage, so the self damage option here can be very useful (its also why I almost never include iron form in the Engine) especially when it can lead to a free dusty Truth Seeker (you could settle for Better Living I suppose). And always remember you have the option to Know When To Hold Fast for some extra emergecy fuel.
When its able to be executed, its a beautiful thing. You can multiple rounds in 4-5 forms just relying on your own deck. Factor in any outside help drawing and Scholar could be going to the races.
Things to look for in teamates: Extra card draws. Healing abilities.
