Elminster + Chakram Retriever + Mystic Speculation

Elminster

Chakram Retriever

Mystic Speculation

How it works

1. Activate Elminster's first loyalty ability by putting two loyalty counters on it, causing you to draw a card and scry 2.
2. Activate a creature by tapping it, adding at least .
3. Cast Mystic Speculation with buyback by paying due to Elminster.
4. Chakram Retriever triggers , untapping the mana-producing creature.
5. Resolve Mystic Speculation, causing you to scry 3 and return it to your hand.
6. Repeat from step 2.

This delightful loop turns the modest act of scrying into a bottomless well of spellcasting by tying Elminster's cost-reducing prowess directly to Mystic Speculation. Because Elminster discounts your next instant or sorcery by the number of cards you look at when you scry, his prior loyalty activation ensures Mystic Speculation can be cast over and over using its buyback cost, returning safely to your hand to fuel the engine. Meanwhile, Chakram Retriever sits quietly on the board, acting as the dynamic mechanical bridge that untaps your mana source every single time you cast that spell on your turn. It’s an elegant, self-sustaining cascade that lets you endlessly dig through your deck while generating limitless storm count and magecraft triggers.
