15 Ratchet, Field Medic // Ratchet, Rescue Racer Starting off we have Ratchet, Field Medic, a 2/4 with lifelink
The reason this is ahead of the other symmetrical draw spells is that it either generates you mana or costs none once it has resolved thus allowing you first dibs on using the new cards and no disparity in mana
When you lose control of this enchantment, put all cards exiled with this enchantment into their owner's graveyard
Very appropriately, the Gruul are a bit less maniacal than the Rakdos, so this card lets you choose whether you want a sturdier or more aggressive creature
Ramp The question you must ask when figuring out your ramp is this: what am I ramping into
I certainly would have paid more if Gravecrawler cost two mana and I didnt need another zombie in play to bring him back
