This is a hybrid deck where I have combined two decks together.
My original Blue Stuff deck slowed down my opponent by restricting his mana and used adaptable, versatile and efficient creatures to stall until I could bring out big creatures like Lorthos, the Tidemaker.
This giant 8/8 for 8 who lets you pay 8 to tap 8 permanents along with 8 lines of text, did I mention he is a legendary Octopus?
Psychic Venom + Power Taint + Mana Leak + Toils of Night and Day
Early game these can really stunt your opponent mana growth and make them think, should they try and rush you and pay life early on, or should they wait the game out? In multi-player spreading these cards around multiple players early can push a stalemate in your favour.
Toils of Night and Day underestimated, gives you the choice of tapping or untapping two permanents, you can also untap and retap the same land to reactivate psychic venom
Dream Stalker
+
Primal Plasma
+
Wormfang Drake
All have great great stats and are good for controlling combat.
Dreamstalker, used to bounce a permanent to your hand to use their effects again. Especially helpful with Halimar Depths, Soaring Seacliff, and Reality Acid, which forces your opponent to sacrifice a permanent, good against lands or indestructible. Wormfang Drake has champion a creature and is used to re-trigger their abilities and lets you hide them away to avoid wrath effects. Aether Spellbomb and Mask of the Mimic lets you control when Wormfang Drake leaves play which lets you control exactly when the creature championed by Wormfang Drake re-enters play. Primal Plasma expensive but gives you a choice,a 1/6 defender, a 3/3, or a 2/2 flyer.
Brain Freeze

Cerulean Wisps

Kaho, Minamo Historian
, Kaho is in this deck for card advantage - you can get 3 extra counterspells, or you can grab 2 whisps and freeze to mill your opponents for 9+ cards and draw two cards all for 4 mana.
Treasure Mage is used to search for Steel Hellkite, and Sharding Sphinx, do not underestimate the Sphinx as they all synergise with Grand Architect which pumps all blue creatures and lets them generate mana for Hellkite and Sphinx.
Grand Architect

Mortarpod
gives all blue creatures sacrifice:ping a creature or a player
