My opinion on why Standard has been stale over the last few years is because there have been a small number of cards that have been much better than the rest of the card pool, which means you had to play them
The Collector Boosters for this set are by far the most interesting offering of the Kaldheim product line, primarily due to their unique packaging
When you need weird specific things and have 1/40 compared to 4/60 your odds are lower and you rely much more on poorer cards that do similar things
Theres also the Gyruda, Doom of Depths combo, where youll cast Gyruda, mill some cards, cast one of the clones or shapeshifters youve just milled (preferably ones that ignore the legend rule), effectively copying Gyruda and its ETB trigger
That means you can expand the experience with booster packs or additional decks, building all new decks or adjusting existing ones to your liking
