Once you've got your first draft of the deck, I suggest you lay it out in stacks organized by mana value
(To proliferate, choose any number of permanents and/or players, then give each another counter of each kind already there.) The value of X is determined only once, as Tromell's last ability resolves
The ability to choose what modes to select when casting the card makes them highly valuable (both in-game and oftentimes monetarily), as you can tailor their decisions based on your own board state
The more people that open these sealed boxes, the more rare the cards get, and prices will only increase as we move forward
If the print run is truly lower, sealed product could become scarceand valuablewithin a few months, especially if other 2025 sets overshadow it and suppress early sales
