Creatures
Curious Homunculus
-> Ramp or threat that makes our spells cheaper. Super versatile card.
Ludevic's Test Subject
-> Protection card that could potentially end the game for us.
Viscerid Deepwalker
-> One-mana 2/3 with a mana-sink ability.
Deep-Sea Kraken
-> Our main finisher. It provides great pressure to our opponent, not to cast too many spells.
Counterspells
Spell Pierce
-> Essential card for the early game. Dodges targeted discard and dangerous burn or removal.
Syncopate
-> Versatile card that we can hopefully use to exile your opponents stuff.
Mana Leak
-> Just a great all round counter-spell in a budget deck.
Psychic Rebuttal
-> You opponent is not going to see it coming, when you flip their spell back on themselves.
Rune Snag
-> Another great counter-spell that gets better the more of them you use.
Support cards
Clockspinning
-> Helps us get our big stuff out a bit earlier. Can also be used to remove/add counters on your opponents stuff.
Opt
-> Gets us through our cards faster.
Foresee
-> Gets us through our cards fasterer.
Elixir of Immortality
-> Awesome ability to keep us alive a little longer in faster match-ups.
Sideboard
Tormod's Crypt
-> Handle decks that interact with the graveyard.
Annul
-> Great against decks with a lot of artifacts or enchantments.
Ceremonious Rejection
-> Super way of handling some difficult Tron pieces for instance.
Damping Sphere
-> High-impact card against a lot of decks like Tron, Storm or Amulet Titan.
Essence Scatter
-> Add in, in case your opponent is a creature-heavy deck.
Psychic Rebuttal
-> More psychic rebuttal, if you run into a deck that targets you a lot.
Monastery Siege
-> Super protection against decks like Burn or Mill. Could also be used for added card-draw if needed.
Engulf the Shore
-> Sort of a board-wipe for the mono blue player.
Talent of the Telepath
-> A card that is going to make your opponent say: 'You can do what now???'
