Sai, Master Thopterist is the most flexible among legendary creatures with this play pattern, as there are plenty of strong artifact-centric strategies that synergize with its effects for building an army or drawing cards as the situation warrants
Vampiric Tutor is the most expensive card in the deck
This red-black Goblin gives you a repeatable way to bring back a Goblin card from your graveyard to your hand each turn
Best of all, they won't take any money until dispatch, so you can secure your Play Booster Box now to avoid disappointment at launch
While I realize theres likely not enough goblin support to make Krenko consistent enough to the point of being broken, and drafting a singular color in a set like CMM is likely not smart, Krenko and Purphoros being in the command zone together seems like something you really dont want to happen
Actually, I'll pull other flyers like Birds of Paradise and move to non-flying support
