The ability will just resolve and the game will continue as normal
In fact, by the time that project was finished, I had read every piece of fiction set on Dominaria, including Arena
The learn cards can also grab Fractal Summoning in case he floods out, so having extra lands isnt particularly concerning
Until then, we just need to keep demanding Creatures (21) 2 Birds of Paradise 2 Kitchen Finks 4 Arbor Elf 3 Inferno Titan 1 Obstinate Baloth 1 Thrun, the Last Troll 2 Huntmaster of the Fells 1 Thragtusk 2 Stormbreath Dragon 3 Tireless Tracker Planeswalkers (3) Lands (22) Spells (14) G/R Ponza decks all look weird at first glance, but they have a bunch of strange elements that all blend together to make something delicious
Cutting that to a list this narrow was a task , not to mention ranking them against each other
I also want to point out that theres a treatment which isnt on this list: EA versions of the original art for the 8 face commanders, which can only be opened in the bundles that comes with two legendary EA cards, and the Collector Booster Sample packs
