I haven't been playing long.
However, I've noticed a lot of players are using sacrifice lands to get what they want to circumvent the random shuffler.
I've played a lot of games and decks that are 1 color and up to 5 colors.
It seems anything over 1 color breaks the card shuffle completely. Then you can't do most combos.
This random draw issue has been going on for years now from several reddit posts I've come across.
This one is really good and breaks it down.

Your stuff is broken. I'm constantly Mana flooded or starved. Even on 1 color decks.
From the looks of it I'm not alone.
Now, since I don't have cards in a abundance to search for basic lands. I have to use mostly basic lands. When I say 3 games in a row I drew every land in the deck and not a single action card is not an exaggeration.
Even if I mulligan, I get mana flooded/starved.
I had such high hopes for this game. I guess I'll shelve it until I hear it's fixed or play it as a non-committal time waster. Kinda like the google dino jump game.
