This deck is a malygos OTK deck with a great board control and high surviving abilities.
Combo is Malygos+double lightning bloom+some damage spells. But if you don’t have enough mana to kill your opponent, you can set a double primordial studies for malygos discount 1 turn before malygos or a rune dagger spell damage boost.
Lightning Storm, Hagatha’s Scheme and Tidal Waves are great for survivability.
Lorekeeper Polkelt can help drawing malygos early.
Ooze is the counterplay of all meta weapons like Rune Dagger, Ceremonial Maul and Self-Sharpening Sword.
Card draw can be a problem. I hope Mana Tide Totem’s and Far Sight’s can solve this problem.
You can add some fun cards like King Phaoris, Bandersmosh or Fist of Ra-den. Have fun!
