Legacy Thought Lash deck
UPDATED MARCH/2022
Thought Lash is a combo deck that has seen some play in the past with the usage of Laboratory Maniac, but the strategy made became even more powerful with the printing of Thassa's Oracle.
Because of that, the deck is also known as Thassa's Oracle Combo, Thought Oracle or Thassa's Lash
Overview
It is a combo deck. However, since Thassa's Oracle is a Merfolk and all combo pieces are Blue, the strategy became an alternate win condition in some Merfolks decks - the implementation did not require much deckbuilding efford and major concessions.
Even though the main win condition of the deck is Thassa's Oracle, the player may also win woth Jace, Wielder of Mysteries and Laboratory Maniac.
Paradigm Shift is a card that operates similarly to Thought Lash. It contributes to the self-mill plan and is also in Blue. Paradigm Shift is often preferred by Merfolks' players instead of Thought Lash for their alternate win condition.
The deck is mostly found in Mono-Blue, but it can also be found splashing White. With Blue, it has access to Force of Will for protection.
The deck itself requires the usage of a couple Reserved List cards: Thought Lash and Paradigm Shift. While they are not hard-to-acquire cards compared to old duals, they may face the same issue Reserved List cards tend to face in the future (scarcity and becoming hard-to acquire).
Therefore the deck is partially welcoming to budget-limited players since Reserved List cards tend to spike in price over time.
