Prison/stax decks stop your opponent from playing cards and attacking you while gaining incremental advantages over time, be it with lifegain, Treasure tokens, or card draw
That is such a silly, tongue-in-cheek geeky solution to this inconsistency, I can't even be mad
To return to the Thalia example, this means that you can use the "Mina Harker" version even if all you have are the Historic Anthology or March of the Machine 's Multiverse Legends printings of Thalia, Guardian of Thraben
It's a blue legendary enchantment that, for two mana, allows you to look at the top card of your deck during every upkeep
Our mana rocks like Astral Cornucopia, Everflowing Chalice, Empowered Autogenerator, Mindsplice Apparatus all generate more mana as we proliferate, our storage lands like Dreadship Reef also become huge rituals, Vat of Rebirth and Lux Cannon get way more effective, we can speedrun through sagas like Phyrexian Scriptures and so much more
Skip this step if you dont have an in-depth understanding of the game
