Meditation +
Twinbrood Sauropod, especially with killer, will give you a high threat density and technically offset the card advantage by drawing two cards with the echo
Meditation +
Auric Interrogator allows you to save your interrogator from a kill spell while simultaneously giving it the buff needed for it's ability activation. The card disadvantage from meditation is then offset by Interrogator's ability
Meditation + Predatory Carnosaur Allows you to play an 8/8 killer next turn.
All of these things can be done at fast speed during opponent's turn so it's not a huge drawback. I think this has a lot of potential. Meditation + clockroaches or pteriax's.
Hope you enjoy the deck and premise. Let me know if you have any adjustments, thoughts, questions, or concerns.
