Your lands can now refill your cup, and if you make sure to have a drink mustache of some kind at the beginning of combat, you get to grow your creatures
The main takeaway is that its nice to be able to reliably find an answer to a tricky permanent, or to pull out a win condition when the game is approaching a natural conclusion
Mana Crypt was one of those cards, along with Arena, Sewers of Estark, Windseeker Centaur, and Giant Badger
but it is the best Omen for finding the cards you need, be they the A to your B, your mega-bomb, or just making sure you draw the right balance of lands and spells
Even if you cant attack with your warped creature right away, you can tap it to station a permanent and add charge counters
Combos and Interactions This deck isnt running any infinite combos but it does have some fun synergies that are worth mentioning
