...contains some metrics to influence the game-play experience that they believe would somehow increase the program's profitability. Tinfoil hat time! Nah, just recognizing that it's a good rule of thumb to err on the side of assuming corruption in an American institution rather than lack thereof. :-) As for the correct number and identities of Oath targets, I would say it varies, but I do not recommend less than three unless you're playing one of the terrible cards to mitigate that (Memory's Journey, Gaea's Blessing, or heaven forbid, Krosan Reclamation). That dead slot is probably just better as creature #3. Chrome Mox, while a dreadful accelerant in many lists particularly on the control side, is surprisingly nice in Oath since you can realize some utility for the otherwise chaff cards in hand, whether they are uncastable creatures, inapplicable nuisance counters v. Shops g1, or redundant copies of Oath of Druids. I liked it a lot, especially as it can help make Tolarian Academy viable.
