I'm gonna give a long answer to hopefully properly address this, and maybe some other things since you seem to have a lot of questions:
My deck is HARD control. It's slow, grindy, draw-go permission style. 99% of my game takes place on my opponent's turn. I am concerned with a series of 1 for 1s, having an answer for everything they throw, and then building incremental card advantage. Game 1 starts, I'm already ahead. Because a certain number of cards are complete blanks with me having no creatures. Which means assuming nothing else, if I just do 1 for 1s, I end up winning.
Then we have the actual active ways to get card advantage. Obvious ones like Chemister's Insight and Ral. But the biggest one for me personally, as you asked about earlier, is Firemind's Research. This is a 2-drop enchantment that just reads "Card Advantage." Think about it this way. Every time I play a card, I get half a card back. Once I realized through play that that's basically what it does, it wasnt a question of keeping it in the deck, but of how many(I'm up to 3). That thing is a monster. And then, of course, Jump-Start gets an honorable mention because it's pseudo-CA in the lategame pitching irrelevant cards(lands).
Then we have the actual burning. Which is pretty simple when you have extra cards to play with. Obviously Ral getting to 8 is an auto-win, but beyond that we have Browbeat 2.0. Which is normally just an 8-damage burn to the face at instant speed(The cards are a wash if you have Firemind's out, because the 2 casts nets you an extra card to pitch). Inescapable Blaze is a solid chunk of life for a single card, again at instant speed, and a great finisher versus control who have let themselves get low on Risk Factors. Especially if you have both and EOT one on their turn, untap, and cast the other. These are the big burners; and then you have incremental damage here and there from Ionize, maybe throwing a lategame Lightning Strike at their dome, Shocking them once instead of discarding down to 7(happens more than you might think, you get a lot of cards). And obviously when you aren't in the card buying business, Firemind's does have another ability that is relevant to this point.
