Indeed, not only we have a clear direction as which kind of characters we want to play, the deck itself focuses on some core card games mechanics, such as efficient challenges, or developing big numbers
The (extremely anecdotal) numbers being passed around by fans right now are about 1 in 100 packs, however, so don't expect to open one anytime soon
If the answers to all these questions are yes, then go ahead and add Gilded Lotus in your deck
this could go absolutely nuts if you could think of a way to copy Orvar by making the legend rule not apply, hopefully there haven't been any cards that copy legendaries but turn them non-legendary, or you'd get an absolutely absurd amount of tokens very quickly
Vivi Ornitier's effect is so good, and can be copied onto other creatures (something Izzet Cauldron decks do in Standard), so they too can provide mana to make for explosive turns where you can play your entire hand and draw a bunch of cards
