This is a very different experience, as Ursula's turns work differently than a player's normal turn
Either way, Ursula, Sea Witch is a great card for neutralising strategies that are built on readying and/or exerting cards
The more colored cards youre using in your sideboard, the more likely you are to want seventeen lands since it usually means four of them are Glimmervoid
In Throne of Eldraine Standard, players have found that Gilded Goose really doesnt play like Birds of Paradise, in that theyre trying to go up the curve to cast cards like Nissa, Who Shakes the World, and finding that their Goose only offers easy mana once can be a little disappointing
There are plenty of cards beyond these that will serve you well if youre drafting, and can be used in a few Commander decks too, but these ones are generally more useful across the board
