Well, i'm definitely wrong at this matter... Deckbuilding just feels pretty different, than MtG one. In draft, i always manage to get lots and lots of good cards from same domain (there's no need in filler cards, no splashes to add 11th creature to deck, ever). Is it really draft?
There was quite different story with sealed (lack of creatures in card pool, especially early drops, was common, and often fatal, problem). But now it's revitalized.
And i cannot force myself to cut constructed deck past 45 cards
On other hand, "minimum" ain't "not more than". So never mind, it's probably good as it is.
P.S. Except draft, which is just... unnatural.
