Im a little less sold on the Investigators, whose two abilities both seems generally useful but not terribly focused here
For any Lorcana card with meaningful raw value, particularly Cold Foil cards and Enchanted Rares which can command significant prices even ungraded, you should use a tracked and insured service without exception
I dont like when cards are this easy to turn into infinite combos, and I really dont like infinite combos to begin with
The card, titled Post, Son of Rich , is a reskin of K'rrik, Son of Yawgmoth , and features Post Malone's likeness in the same pose and outfit as the Phyrexian minion
I wouldnt tunnel in on Grixis too early, but if you are drafting blue/red and havent seen any good payoffs, consider picking black removal and going the Grixis direction
My next recommendation comes in the form of Aeronaut Admiral
