The massive card flow that people want for free in Commander and multiplayer lead them to attack each other, but not you, especially since they don't have to spend a card to get the card draw, so for them, this is free card advantage over time for each foe that attacks each other, and you'll draw more than the card it took to cast him in one or two turns
There's really only one takeaway from this, and that takeaway is prices of Final Fantasy sealed product, and specifically Final Fantasy collector booster boxes, are just way too high to be opening right now. As a comparison about price points, consider that you can get all four of the Final Fantasy Commander precons for around $400 at the time of writing so you could but all four Precons, and a couple of Play Booster Boxes, and spend roughly the same as just one single Collector Booster box
And some other stuff, I suppose
But the outcome is too beneficial to ignore
Magic has messed around in this space many times (threshold, flip cards, level-up, etc.)
