Luis and I will talk about these cards on episode 290 of LR as well, well see you there
Fear, Fire, Foes
That fuel typically comes in the form of low-cost creatures, and Greedy Freebooter is about as good as it gets in that arena
Gallifrey Falls // No More I love cards with dual affects, and if you have enough mana, you can maximize Gallifrey Falls / No Mores two sides by fusing it to make a great one-sided board wipe
Dragonologist Dragonologist does a little bit of everything you want early on: It digs for dragons, instants, or sorceries when it enters, and then once you start dropping your dragons, it gives them hexproof as long as they stay untapped
